 Title    Condensed [Ru4Sn6] Units in the Stannides LnRu4Sn6 (Ln = La, Pr, Nd, Sm, Gd) -Synthesis, Structure, and Chemical Bonding  
 Abstract    The stannides LnRu4Sn6 (Ln = La, Pr, Nd, Sm, Gd) were prepared by reaction of the elements in an arc-melting furnace and subsequent annealing at 1120 K. The praseodymium, the neodymium, and the samarium stannide were obtained for the first time. The LnRu4Sn6 stannides were investigated by X-ray diffraction both on powders and single crystals. They adopt the YRu4Sn6 type structure which was refined from single crystal X-ray data for the samarium and the gadolinium compound: /42m, a = 686.1 (1), c = 977.7(2) pm, wR2 = 0.0649, 483 F2 values for SmRu4Sn6, and a = 685.2(1), c = 977.6(3) pm, wR2 = 0.0629, 554 F2 values for GdRu4Sn6 with 19 variables for each refinement. The striking structural motif of these stannides are distorted RuSnö octahedra with Ru-Sn distances ranging from 257 to 278 pm. Four of such octahedra are condensed via common edges and faces forming [Ru4Snö] units which are packed in a tetragonal body-centered arrangement. The rare-earth atoms fill the voids between the [Ru4Sn6] units. Based on an extended Hückel calculation, strong bonding interactions were found for the Ru-Sn and the various Sn-Sn contacts.

 Title    The Stannides RE R hSn (RE = Ho -Yb) and ScTSn (T = Pd, Pt) -Structure Refinements and 119Sn Mössbauer Spectroscopy  
 Abstract    The stannides RERhSn (RE = Ho -Yb) and ScTSn (T = Pd, Pt) were prepared by reaction of the elements in sealed tantalum tubes in a high-frequency furnace, by arc-melting, or by a tin-flux technique in quartz tubes. The rhodium based stannides crystallize with the ZrNiAl type structure, space group P62m. The four structures were refined from single crystal X-ray data: a = 754.5(3), c = 377.1(1) pm, wR2 = 0.0357, 233 F 2 values for HoRhSn, a = 753.3(1), c = 372.16(8) pm, wR2 = 0.0721, 233 F 2 values for ErRhSn, a = 753.7(3), c = 369.0(2) pm, wR2 = 0.0671,233 F 2 values for TmRhSn, and a = 753.17(5), c = 366.53(4) pm, wR2 = 0.0566, 180 F 2 values for YbRhSn with 14 parameters for each refinement. ScPdSn and ScPtSn adopt the HfRhSn type, a superstructure of ZrNiAl, space group P62c: a = 747.5(1), c = 710.2(1) pm, for ScPdSn, and a = 738.37(9), c = 729.47(9) pm, wR2 = 0.0452,369 F 2 values, 18 variables for ScPtSn. Structural motifs in these stannides are transition metal centered trigonal prisms formed by the rare earth and tin atoms. While these prisms are regular in the rhodium based stannides, significant distortions occur in ScPdSn and ScPtSn. The formation of the superstructure can be ascribed to packing reasons. The shortest interatomic distances occur between the transition metal (T) and tin atoms. These atoms form three-dimensional [FSn] networks in which the rare earth atoms fill distorted hexagonal channels. The series RERhSn displays a somewhat unique behavior. The a lattice parameter is more or less independent of the rare earth element, while the c lattice parameter shows the expected lanthanoid contraction. ll9Sn Mössbauer spectroscopic data of the rhodium stannides show signals at isomer shifts varying from 1.77 to 1.82 mm/s subject to quadrupole splitting between 0.75 to 0.82 mm/s.

 Title    Synthesis, Structure, and Magnetic Properties of EuAgCd and YbAgCd  
 Abstract    New intermetallic compounds EuAgCd and YbAgCd were synthesized in quantitative yield by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Both com­ pounds were investigated by X-ray diffraction on powders and single crystals: KHg2 type, Imma, a = 490.41(8), b = 771.0(1), c = 834.4(2) pm, wR2 = 0.0624, 255 F values, 12 variables for EuAgCd, and MgZn2 type, Pb^/mmc, a = 584.66(5), c = 946.83(9) pm, wR2 = 0.0502, 187 F 2 values, 11 variables for YbAgCd. Owing to the very small difference in scattering power, no long range ordering of the silver and cadmium atoms is evident from the X-ray data, although Ag-Cd ordering is expected. The silver and cadmium atoms randomly occupy the mercury and zinc positions of the KHg2 and MgZn2 type structures, respectively. In EuAgCd the [AgCd] substructure consists of strongly puckered, orthorhombically distorted Ag3 Cd3 hexagons, while a three-dimensional network of face-and comer-sharing tetrahedra is observed in YbAgCd. The rare earth atoms fill the space between the Ag3 Cd3 hexagons (EuAgCd) or within the three-dimensional tetrahedral network (YbAgCd). Magnetic susceptibility measurements in­ dicate Pauli paramagnetism for YbAgCd and Curie-Weiss behavior above 60 K for EuAgCd with an experimental magnetic moment of 7.82(3) /j b/Eu indicating divalent ytterbium and europium. Ferromagnetic ordering at Tc = 28.0(5) K is observed for EuAgCd. At 2 K and 5 T the saturation magnetization is 5.85(5) /iß/Eu.

 Title    Glycerol Conformation and the Crystal Structure of Lipids. I. An Electron Diffraction Study of Tripalmitin and Conformationally Fixed Analogs  
 Abstract    Transmission electron diffraction is used as a qualitative analytical probe of poly methylene chain packing in three conformationally-restricted analogs of tripalmitin derived from configura­ tional isomers of cyclopentane-l,2,3-triol. The analysis demonstrates that the all trans "tuning-fork" conformation seen in X-ray crystal structure analyses on homologous compounds is also found in microcrystals, in contrast to a proposal by Fringeli et al. (Z. Naturforsch. 27 b, 780 [1972]) that an all cis conformation of the triglyceride exists in solvent-grown microcrystals and in multilayers. The presence of mixed polymorphs is also shown for bulk samples previously examined by X-ray powder diffraction techniques by other workers.

 Abstract    One of the diastereomeres of 2,3,4,6,7,8-hexamethyl-2,3,4,6,7,8-hexaphosphabicyclo-[3,3,0]octane (PMe)öC2H2 crystallizes in the space group P2i/n with four molecules per unit cell. Two independent molecules are nearly identical in shape but differ by inter-molecular packing. The five-membered rings have a skew chair conformation with all exocyclic methyl groups in axial positions leading to a staggered all-trans conformation of the bicyclic system. The mean bond lengths are P-P = 220.9 pm, P-C = 185.9 pm and C-C = 151.9 pm.

 Title    Synthese und Kristallstruktur von C83(AuBr 4 ) 2 Br3 Synthesis and Crystal Structure of Cs3(AuBr4) 2 Br 3  
 Abstract    Cs3(AuBr4)2Br3 is obtained in the form of red needles by adding the stoichiometric amount of CsBr to a solution of HAuBr4 and Br3~ in aqueous HBr. The salt decomposes slowly at room temperature to form a mixed-valent, cubic bromo aurate(I,III), in which the linear AuBr 2 ~ ions are partially substituted by Br3~ ions. At 140 °C Cs 2 Au 2 Bre and CsBr are formed. Cs3(AuBr4) 2 Br3 crystallizes monoclinic with four formula units in the space group P2i/c. The structure is built up by AuBr 4 ~ and Br3~ anions and Cs+ cations. An average Au-Br distance of 242.2 pm was found for the square planar AuBr 4 ~ ion. The linear Br3~ groups are almost symmetrical with Br-Br distances of 254.0 and 256.2 pm. Therefore only two vibrations are observed in the IR spectrum: Vas = 172, <5 = 56 cm -1 . The absorptions of the AuBr 4 _ groups are: vas = 250, <5as= 113, y — 102 cm -1 .

 Abstract    A congruently melting phase of molar ratio 2:3 was identified in the system SbCl3/4-phenylpyridine. The structure consists of two different types of complex units: One SbCl3 molecule is bonded to one 4-phenylpyridine ligand only, whereas the other one forms a complex with two 4-phenylpyridine ligands. The SbCl3 unit in the 1:1 species is pyrami-dally shaped, whereas the SbCl3 unit in the 1:2 species displays a T-shaped geometry. The mean angle between the phenyl and pyridyl planes is 33.3°; mean bond lengths are <Sb-Cl> = 247.6 pm and <Sb-N> = 241.7 pm.

 Title    Darstellung und Kristallstruktur von Tl 2 TiS 4 : Ein Perthiotitanat(IV) mit i-[TiS 4 2 "]-Ketten Preparation and Crystal Structure of Tl 2 TiS 4 : A Perthiotitanate(IV) with ^-[TiS 4 2 ~]-Chains  
 Abstract    Tl 2 TiS 4 is orthorhombic, space group Pbca, with a = 22.176(7), b = 9.484(4), c = 6.3977(9) A, Z = 8. The crystal structure was solved by direct methods and refined to a conventional R of0.058 for 704 reflections with I^3a(I). The crystal structure is characterized by infinite perthioanions, i-[TiS 4/2 (S 2) 2 -], which are separated by Tl + -cations. The anion chains are built up by distorted octahedra which share two skew edges to form infinite cis-chains running along [001], The two unshared S-atoms of each octahedron are connected via a S —S-single bond of 2.10 A length. The crystal structure is described as a mixed packing of TI-and S-atoms, composed of puckered T1S 2 -layers, in which the Ti-atoms occupy the octahedral interstices. The relationship of the ^-[XiS^ -]-chains to the anionic groups of Cs 2 TiS 3 is discussed.

 Title    Reactions of the Hexafluorothioacetone Dimer with Cyanides of Phosphorus, Arsenic and Germanium  
 Abstract    Cyanides such as P(CN) 3 , As(CN) 3 , PhP(CN) 2 , Bu'As(CN) 2 and Ge(CN) 4 react with [(CF 3) 2 CS] 2 (1) by insertion of the carbon atom of the /so-nitrile isomer into the four-mem-bered [CS] 2 ring to give compounds PR 3 (2), AsR 3 (3), FP(S)R 2 (4), PhP(S)R^ (5), Bu'AsR^ (6) and GeR 4 (7) respectively, where R' is the novel heterocyclic ligand —N=C—S—C(CF 3) 2 —S —C(CF 3) 2 . The crystal structures of 3 and 7 are reported.

 Title    Oxidative Knüpfung einer Phosphor-Phosphor-Bindung unter Einwirkung von Ag(I)-bzw. Cu(II)-Ionen: Synthese und Struktur von [(C 6 H5)PH 2 Ag{|i-(C 6 H 5 PH) 2 }]2 (AsF 6 ) 2 , einem sechsgliedrigen Silber-Phosphor-Ring The Oxidative Formation of a Phosphorus-Phosphorus Bond in the Presence of Ag(I) and Cu(II) Ions: Synthesis and Structure of [(C 6 H 5 )PH 2 Ag{^-(C 6 H 5 PH) 2 }] 2 (AsF 6 ) 2 , Containing a Six-Membered Silver-Phosphorus Ring  
 Abstract    The reaction between AgAsF 6 and phenylphosphine proceeds with formation of a phosphorus-phosphorus bond. The main product 1, [(C 6 H 5)PH 2 Ag{u-(C 6 H 5 PH) 2 }] 2 (AsF 6) 2 , was characterized by an X-ray structure determination [PI, a = 919.0(4), b = 1109.8(4), c = 1316.4(5) pm, a = 97.48(3), ß = 107.25(3), y = 102.71(3)°, Z = 1, R = 0.057 for 2806 observed reflections], 1 contains Ag 2 P 4 rings; the silver atoms are further coordinated by phenylphosphine ligands, thus acquiring trigonal coordination geometry. A similar reaction is observed with Cu(AsF 6) 2 , forming the analogous Cu(I) complex 2.
