 Title    X-Ray Structural Analysis and Vibrational Spectra of Sodium Cysteine-S-sulfonate, +H3N C H (C 0 0 )CH 2S 20 3Na -3 /2 H 20 [1]  
 Abstract    The title com pound crystallizes orthorhombically (space group C 222,) with a = 797.0, b = 870.3 and c = 2739.0 pm. The anions are zwitterions which are heavily involved in intra-and intermolecular NH --O and OH -O hydrogen bonding. The two types o f sodium cations are coordinated by six oxygen atoms each o f which belongs to either S 0 3 groups (N a 2) or water molecules and S 0 3 groups (N a l). A second type o f water molecules is not coordinated to the cations. The SS bond length is 208.2 pm. Infrared and Raman spectra o f the title com pound are reported and tentatively assigned. The SS stretching vibration is observed at 409 cm -1.

 Title    Reaktionen von Pyridin-Basen mit Na/K-Legierung und Diorganylaminodifluorboranen Reactions o f Pyridine-Bases with Na/K-Alloy and D iorganylam inodifluoroboranes  
 Abstract    Lutidines react with N a/K alloy and diorganylaminodifluoroboranes in «-hexane. The products formed depend upon the position o f the methyl groups. While from 3,4-lutidine (C) the bis(lutidinyl)am inoboranes 2 -5 are obtained, the 2,4-, 2,5-, and 3,5-lutidines (F, G, H) give the 11 a, 1 lb-dihydro-[l,3,2]-diazoborolo-[5,l-b;3,4-b']-dilutidines 1 1 -1 7 . 4-Picoline reacts analogously to give 10. Pyridine (A) and collidine (B) give adducts with borane. From 2,3-lutidine (D), the 1,4-dihydro-l,4-bis(fluoram inoboryl)-2,3-lutidine 8 is obtained. 'H, "B, l3C, 19F, -9Si, 15N N M R and MS data are given. For 8 and 14 the X-ray structures are reported.

The adduct tolu ene-2 HC1, melting incongruently at -1 1 5 °C, is monoclinic with space group C 2 /c and Z = 4 formula units per unit cell; the adduct mesitylene-HCl, m .p. -6 4 °C, is orthorhom bic with space group P bca and Z = 8. The HC1 molecules are situated on both sides and one side, respectively, o f the plane o f the aromatic system and are linked to it by weak hydrogen bonds o f the type C l-H — it.

M olecular Structure of [C5Cl2(SMe)2(PPh2)]Mn(CO)3 The reaction o f [C5Cl4(SM e)]M n(CO)3 (la) with «-butyllithium and the electrophiles SiM e3Cl, C 0 2, or PPh,Cl regiospecifically yields the chiral 1,3-disubstituted functional cym an­ trene thioethers [C5Cl3(SM e)R]M n(CO)3 (R = SiM e3 (2), COOLi (3a), PPh2 (4)). 3 a can be protonated to give the corresponding carboxylic acid (3 b), which in turn can be transformed to the acid chloride [C5Cl3(SM e)(COCl)]M n(CO)3 (3c). 3c reacts with N a N 3 to yield after work-up the urea derivative O C [[N H -C 5Cl3(SM e)]M n(CO)3]2 (3d). U sing the cymantrene bis-thioethers [C5Cl3(SR)2]M n(CO)3 (R = Me, 5a, Ph, 5b) as starting materials, the carboxyl de­ rivatives [C5Cl2(SM e)2(COR)]M n(CO)3 (R = OLi, 6a, OH, 6b, Cl, 6 c) and the potential organometallic S,P-chelate ligands [C5Cl2(SR)2(PPh2)]M n(CO)3 (R = Me, 7 a , Ph, 7b) can be obtained. The crystal structure determination o f 7a (C " H 160 3PS-,CLMn, m onoclinic, P 2,/c, a = 18.714(6) A, b = 9.506(3) A, c = 14.475(3) A, ß = 109.18(2)°, V = 2432.1(12) A \ Z = 4) shows an orientation o f the neighbouring PPh2-and SMe groups, that allows chelation o f an additional metal fragment.

 Title    Syntheses and Structures of Three Mononuclear Coordination Compounds Containing Six-and Seven-Coordinated Manganese(II) Ions  
 Abstract    The reactions o f M n(C F3COO)2 (1) with N ,N,N ',N '-tetram ethylethylenediam ine (tmen), 2,2'-bipyridine (bipy) and triethanolamine (tea) yield three new mononuclear coordination compounds: rra«5-[Mn(tmen)2(C F3COO)2] (2), cw-[M n(bipy)2(C F 3COO)2] (3), and [M n(tea)2](C F3COO)2 (4). The X-ray structures o f the com pounds 2, 3, and 4 are described. The seven-coordination o f the manganese(II) ion in 4, as well as the inequivalency o f the two tea molecules coordinated to Mn(II) make this com pound unique.

 Title    Darstellung, UB-, 13C-NM R-und Schwingungsspektren der c/öso-Hexaborate [B6H 5(C N )|2~ und m -[B 6H4(CN)2l2_ sowie Kristallstruktur von Cs2[B6H 5(CN)|  
 Abstract    of the c/oso-Hexaborates [B6H 5(CN)]2~ and c/s-[B6H 4(C N)2]2-, and the Crystal Structure o f Cs2[B6H 5(CN)] By reaction o f Cs2[B6H 6] with in situ generated dicyanogen in aqueous alkaline solution the m onocyanohydrohexaborate C s2[B6H5(CN)] and the dicyanohydrohexaborate cis-Cs,[B6H4(C N)2] are formed. The com pounds have been separated by ion exchange chrom atog­ raphy on diethylaminoethyl cellulose. The crystal structure o f Cs2[B6H5(CN)] was determined from single crystal X-ray diffraction analysis; monoclinic, space group P 2 Ja with a = 9.540(8), b = 9.977(3), c = 10.578(2) Ä, ß = 105.06(2)°. The B6 octahedron is compressed in the direction o f the nearly linear B -C N bond by about 5%, with bond lengths between 1.71 and 1.76Ä . The "B N M R spectra o f the two com pounds reveal the features o f substituted B6 cages with C4v and C2v point symmetry. In the l3C N M R spectrum o f Cs2[B6H 5(CN)] a quartet at -139 ppm with '/(C ,B) 92 Hz is observed. The IR and Raman spectra exhibit very strong CN stretching bands for Cs2[B6H5(CN)] at 2149, and for m -C s2[B6H4(C N)2] at 2170 c tr r 1.

 Abstract    The green insoluble TiIV compound which is obtained by treating titanocene with HC1 reacts with PhLi to yield the fulvalene-bridged com pound [CpTiPh2]2(C l0H 8) 3(Ph). An X-ray struc­ ture analysis o f 3(Ph) shows, that the Ti atom s are in a trans arrangement with respect to the fulvalene group. Crystal data for 3(Ph) are as follows: C44H3gTi2, orthorhom bic, space group P 2 ,2 ,2 ,, with a = 11,3 8 5(2),/)= 14,510(2), c = 19,489(4) A, Z = 4. The crystals exhibit enan-tiomorphism.

 Title    Bis(di-terf-butylphosphino)ethan-nickel(0)-Komplexe Bis(di-/erf-butylphosphino)ethane-nickel(0) Complexes  
 Abstract    Alkenes, Ethyne, Nickel(O), Phosphane, X-Ray Ni(cdt) reacts with 'Bu2PC2H4P'Bu2 in pentane at 20 °C to yield brownish crystals o f ('Bu2PC2H4P'Bu2)Ni(^2-C |2H ]S) (1). The molecular structure o f 1, as established by X-ray crys­ tallography, exhibits a trigonal-planar coordination geometry o f the nickel center with a rj2-bonded cdt ligand. In the crystal 1 exists as two enantiomers, which are determined by the left-or right-handed screw axis o f the cdt ligand. The cdt ligand in 1 resists most typical displace­ ment reactions but 1 reacts with CO at -7 8 °C to afford the colorless 18e complex ('Bu2PC2H4P'Bu2)N i(C O)2 (2). From the reaction o f N i(cod)2 with 'Bu2PC2H4P'Bu2 yellow needles o f ('Bu2PC2H4P'Bu2)N i(/72-cod) (3) are obtained. Low temperature N M R spectroscopy established that only one diene C = C bond is coordinated to nickel(O). At higher temperatures a rapid exchange o f the coordinated and unbound C = C bonds is induced. When solutions o f 3 are kept at 20 °C for several days the dinuclear, almost insoluble yellow complex {('Bu2PC2H4P'Bu2)N i}2(yU-/72,^2-cod) (4) precipitates. The reaction o f N i(C 2H 4)3 and 'Bu2PC2H4P'Bu2 affords orange ('Bu2PC2H4P'Bu2)N i(C 2H4) (5). From N i(l,5-hexadiene)2 and 'Bu2PC2H4P'Bu2 in 1,5-hexadiene the yellow-greenish complex ('Bu2PC2H4P'Bu2)Ni(>72-C6H 10) (6) is obtained. As for 3, only one diene C = C bond is coordinated to nickel(O), but the struc­ ture is fluxional with exchange o f the coordinated and unbound C = C bonds (N M R at 20 °C). From a solution o f 6 in pentane the dinuclear, diastereomeric com pounds rac/meso-{('Bu2PC2H4P'Bu2)N i}2(//-?/2,?/2-C6H 10) (7a,b) separate in large yellow crystals. In similar reac­ tions the 1,6-heptadiene complexes ('Bu2PC2H4P'Bu2)Ni(//2-C7H 12) (8) and rac/meso-{('Bu2PC2H4P'Bu2)N i}2(//-?72.?72-C7I-[12) (9a,b) are also obtained. In 6, 7 a ,b , 8, and 9 a ,b the open-chain diene ligands can easily be displaced, e.g ., by ethene to afford 5. Thus, complexes 6, 7 a,b , 8, 9 a ,b are the most reactive. These complexes react readily (the ethene derivative 5 also reacts but very slowly) with butadiene to yield large yellow cubes o f ('Bu-,PC2H4P'Bu7)Ni(>72-C4H 6) (10), which is also fluxional. The alkene complexes 5, 6, 7 a,b, 8, 9 a ,b , 10 react with ethyne to yield yellow-brownish crystalline (,Bu1PC-,H4P'Bu2)Ni(C^H2) (11).

 Title    The Crystal Structure of Cesium Fluorotrioxosulfate(VI), C s S 0 3F  
 Abstract    Cesium Fluorotrioxosulfate(VI), Crystal Structure The crystal structure o f C sS 0 3F was deter­ mined from single-crystal X-ray data as tetrag­ onal. space group 14,/am d, with a = 5.6317(2), c = 14.1991(9) A and Z — 4. The structure was refined to R = 0.028, Rw = 0.028 for 403 unique reflections. In contrast to the earlier literature C sS 0 3F is not isom orphous with scheelite but with a -C sR e 0 4. The structure contains isolated S 0 3F tetrahedra which are linked together by twelve­ fold coordinated Cs ions. The average S —0 ,F dis­ tance is 1.453(3) A.
