 Title    Structural Change of a Linear Polyether upon Complex Formation. l.ll-Bis(2-acetylaminophenoxy)-3.6.9-trioxaundecane and its KSCN Complex"  
 Abstract    The title compound (1) was crystallized as free ligand and as its (1 • KSCN)2 • H20 complex. Crystallographic data are, for the former: space group C 2/c, a — 31.110(9), b = 4.608(4), c = 17.188(6) A, ß = 105.27(8)°, Z = 2, Dm = 1.25 gem-3 ; for the latter: space group P2i, a = 11.044(3), b = 18.310(4), c = 14.485(4) Ä, ß = 97.49(2)°, Z = 4, Dm = 1.27 gem -3 . Crystal structures were solved by direct methods using X-ray diffrakto-meter data and least squares refinements converged at 10.8% for 1 and at 7.6% for (1 • KSCN)2 • H20. The free ligand (1) is S-shaped and, upon K+-complexation, changes signs of some gauche O-C-C-O torsion angles while C-C-O-C angles remain trans. In (1 • KSCN)2 • H20, there are two complex molecules 1 A • KSCN • H20 (I) and 1 B • KSCN (II). The ligands are wrapped circularly around K + and coordinated with only four of the five polyether oxygens. K+ interacts further with H20 in (I) and with N of SCN~ in II and, in both complexes, with acetylamino oxygen of adjacent 1. The latter interaction leads to polymeric structures not observed previously for similar complexes.

 Title    Zur Kenntnis der Hydrate des Mangan-und Zinksulfits. Röntgenographische, thermoanaly tische, Raman-und IR-spektroskopische Untersuchungen  
 Abstract    X-ray, IR and Raman data as well as thermoanalytical measurements (DTA, TG, and DTG) of several new hydrates, viz. MnS03 • 2 1 /z H20, MnS03 • 2 H20, ZnS03 • 3 H20, /S-ZnS03 • 2 1 /2 H20, and y-ZnS03 • 2 x /2 H20, and of previously reported hydrates in the systems MnS03-H20, ZnS03-H20, and MnS03-ZnS03-H20 are presented. Furthermore, the formation of mixed crystals is studied in the system MnS03-ZnS03-H20. The following crystal data have been determined by single crystal measurements: MnS03 • 2 1 /2 H20 (P4i2i2):a = b = 968.4(1), c = 1040.9(1) pm, Z = 8, MnS03 • 2 H20 (P2i/w):a = 650.9(1), b = 873.8(1), c = 774.7(1) pm, ß = 99.80(1)°, Z = 4, ZnS03 • 3 H20 (Pnma): a = 953.6(1), b = 553.0(1), c = 941.9(1) pm, Z = 4, ß-ZnS03 • 21/2 H20 (P4i2!2): a = b = 952.1(1), c = 1025.4(1) pm, Z = 8, y-ZnS03 • 2 X \2 H20 (with small amount of Mn 2 +) (o-rh.): a = 1493(1), b = 1812(2), c = 753(1) pm, Z = 16, ZnS03 • 1/2 H20 (mon.): a = 1326.7(5), b = 706.3(2), c = 834.4(1) pm, ß = 117.41(3)°, Z = 8. The IR spectra show that, with the exception of y-ZnS03 • 2 x /2 H20, both weak and strong hydrogen bonds are present in the sulfite hydrates. Under an S02 atmosphere the sulfite hydrates can be dehydrated without simultaneous dissociation to the oxide and sulfur dioxide. The isotypic hydrates /?-MnS03 • 3 H20 and ZnS03 • 3 H20 (ß-MnSÖ3 • 3 H20 type), and MnS03 • 2 H20 and ZnS03 • 2 H20 (ZnSe03 • 2 H20 type) form complete mixed crystal series. Solid solutions are also formed from a-MnS03 • 3 H20 (a-FeS03 • 3 H20 type), y-ZnS03 • 2 l /2 H20, MnS03 • 1 H20, and ZnS03 • 1 /2 H20. No incorporation of Mn or Zn could be observed for a-ZnS03 • 2Va H20 and the isotype hydrates MnS03 • 2!/a H20 and ß-ZnS03 • 2 1 /2 H20 (CoS03 • 21/2 H20 type).

 Title    Methylen Verbindungen von Nichtmetallen, III [1] Metallcarbonyl-Komplexe mit methylenverbrückten Diphosphor-Liganden Methylene Compounds of Non-Metals, III [1] Metal Carbonyl Complexes of Methylene-Bridged Diphosphorus Ligands  
 Abstract    Compounds of the type R2PCH2PR2 (R = Pr«0, Me2N) react with cis-LM(CO)4 (L = Bicyclo[2,2,l]hepta-2,5-dien; M = Cr, Mo, W) complexes to yield cis-substituted [R2PCH2PR2]M(CO)4 derivatives. The structure of the molybdenum compound, [(Pr i O)2PCH2P(OPr i)2]Mo(CO)4, has been determined. Diphosphorus ligands of the type R2P(S)CH2PR2 (R = F, Pr*0) are monodentate and form [R2P(S)CH2PR2]2Mo(CO)4 complexes, whereas the compound (Me2N)2P(S)CH2P(NMe2)2 acts as a bidentate ligand.

 Title    Crystal and Molecular Structure of l,ll-bis(Tropolone)-3,6,9-trioxaundecane * Rbl a  
 Abstract    The complex between the polyether ligand l,ll-bis(tropolone)-3,6,9-trioxaundecane and Rbl crystallizes in space group P2i/c with cell dimensions a — 11.383(4), b = 14.493(5), c = 16.122(6) A and ß = 111.02(5)° with Z = 4. The structure was solved on the basis of 3734 X-ray reflections measured on a diffractometer with CuKa-radiation and refined to an R of 0.101. The polyether wraps around the Rb + in a circular structure. One of the tropolone rings is elevated in order to avoid collision. Rb + is located 1.224(6) A above the plane formed by five oxygen atoms of the ligand, it is coordinated to I -(3.666(2)Ä) and to all oxygens. The Rb+ • • • O distances of the least electronegative "ester oxygens", 3.14(1) A and 3.18(1) A are significantly longer compared to the other Rb+---0 distances in the range 2.81(1) A to 3.08(1) A. The conformation about the C-C and C-0 bonds of the ligand are gauche and trans as generally found in such molecules. The two tropolone seven-membered rings are slightly non-planar and display an envelope-type structure.

 Title    Ternäre Gamma-Messing Phasen in den Systemen Calcium-M IB(IIB) -Quecksilber New Ternary Gamma-Brass Phases in the Systems Ca-M iB(nB)_Hg  
 Abstract    A series of new ternary intermetallic com-pounds of the general composition CaißMi8IB(IlB)_Hg18 (M = Zn, Cd, Hg, Cu, Ag and Au) has been identified. The X-ray powder diffraction patterns were indexed on a basis of primitive cubic unit cells. From the X-ray data and density measure-ments it is concluded that these phases belong to the partially disordered (Ml B (HB) and Hg) gamma-brass structure type D83.

 Title    Radicals Produced in Single Crystals of Thymine Derivatives by UV and X-Rays  
 Abstract    Single crystals o f anhydrous thym ine (T), thym ine monohydrate (T ■ H 20) , 5,6-dihydrothym ine (T H 2), 1-methylthymine (mT) and thym idine (dT) were irradiated with X-rays and UV between 77 K and 300 K. Six types o f radicals were analyzed by ESR-spectroscopy at 9.5 G H z and 35 G H z after exposure to X-rays. The anion radical occurred only in T • H 20 at 77 K, the 4-yl radical only in T H 2 at 77 K and the 1-yl radical only in T between 77 K and 300 K. The 6 -yl radical was found in T, T H 2 and mT. It was converted into the 5-yl radical irreversibly by heat or white light (A < 600 nm). The 5-yl radical appeared in all compounds at room temperature. The highest thermal stability was found for the 7-yl radical which was present at room temperature in all compounds except T H 2 . U V -irradiation (A = 320 nm) produced radicals only in three crystals (T, T H 2 , dT). In T the 5-yl radical was found after exposure at 300 K, and two other radicals, 1-yl and 7-yl, at 77 K. A lso at 77 K, the 7-yl radical was present in dT and the 5-yl radical in TH 2 and dT.

 Abstract    The crystal and molecular structure of the compound Sn3(NC(CH3)3)4H2 has been determined from X-ray data (R = 0.044). The crystals are cubic, space group Pa3, with cell dimension a — 1713.6(8) pm and Z = 8. The molecules, which have a seco-norcubane like Sn3N4 framework, are statistically disordered, thus forming closed packed pairs of molecules. The Sn3N4 cage deviates strongly from a cube, the bond angles at Sn approach-ing 80°, and at N 100°. The averaged Sn-N bond distance is 223(1) pm.

 Title    Die Struktur des Rubidiumtrimolybdathydrats Rb2Mo3O10 * H20 The Structure of the Rubidiumtrimolybdate Hydrate Rb2Mo3Oi0 * H20  
 Abstract    For the first time single crystals of tri-molybdate were obtained through a slow trans-formation of the primary precipitate in a slightly acidified solution of rubidium molybdate at a temperature of 70 °C. A structural analysis of Rb2Mo30io • H20 revealed that the anion forms a chain with a hexameric identity period built up from MoOg octahedra. Each Mo atom is bonded with two terminal oxygen atoms. The anion doesn't contain OH groups.

 Title    Spektralreines Bis(phthalocyaninato)protactinium(rV) Spectroscopically Pure Bis(phthalocyaninato)protactinium(IV)  
 Abstract    Spectroscopically pure PaPc2 has been prepared by reaction between Pal4 • 4 CH3CN and o-phthalic acid dinitrile in 1-chloronaphthalene followed by sublimation at 5 • 10~ 3 Pa in a temperature profile with three clearly defined zones (520 °C/350 °C/room temperature). This procedure gives a product almost completely free of H2Pc impurity which is known to have been present in previously reported complexes of the type AnPc2. Thus, the trace of H2Pc in the substance could only be detected by derivative spectroscopy. X-ray powder diffraction shows the compound to be isostructural with ThPc2 and UPc2. The ligand spectrum is typical of AnPc2 complexes, f-f Bands observed in a solid state spectrum provide additional proof that the compound is Pa IV Pc2.

 Title    und die Röntgenstrukturanalyse eines phosphorhaltigen achtgliedrigen SN-Ringes Synthesis of Four-and Eight-Membered Heterocycles Containing Sulfur, Nitrogen and Phosphorus and the X-ray Structure of a Phosphorus-Containing Eight-Membered SN-Ring  
 Abstract    Eight-membered rings of the composition [S02(NR)2PR']2 3a-d with R = CH3, C2H5, and R' = CH3, CßHs, were prepared from substituted sulfamides and dichlorophosphanes in the presence of a tertiary amine. These molecules were characterized on the basis of X H and 31 P NMR investigations and of mass spectra. 3 a reacts with phosphorus penta-chloride to yield the spirocyclic derivative 4 with the phosphorus atom in the center of two four-membered rings. Methyliodide reacts with 3 a and 3 b under opening of the eight-membered ring and formation of phosphonium salts. The structure of 3 b is discussed in detail. 3b crystallizes in the orthorhombic space group Pna2i with a = 12.60(0), b = 13.27(1), c — 12.62(4) A.

 Abstract    The two stereoisomeric a-azidochalkones (1,3-diaryl-2-azidopropenones) are selectively obtain-able, depending on the temperature, by conden-sation of aldehydes with a-azidocarbonyl compounds. For the higher melting point compound the trans configuration is proved by single crystal X-ray analysis of its triphenyl-phosphazeno derivative. Analogous isomers may now be characterised from their X H NMR parameters.

 Abstract    The preparation of the six-membered rhenacyclohexanes (OC)4ReP(R2)OCH2C(CH3)2CH2 (la, b) [R = CH3 (a), C6H5 (b)J is accomplished by heterolytic cleavage of the Re-Re bond in the binuclear anions [(0C)4ReP(R2)0]2 2 -with strong electrophiles like the alkane-diylbis(triflate) (CH3)2C(CH2Y)2 (Y= OSO2CF3), followed by an attack of the a>-positioned carbenium-like C atom on the phosphinite oxygen of the anion. 1 a, b insert SO2 under ring I I
