 Title    Molekülstruktureii, Schwingungsspektren und Konformation der Thiooxalsäurederivate CH3S-CO-CONH2, CH3S-CS-CONH2, C2H50-C0-CSNH2 und K[OSC-CONH2] Molecular Structure, Vibrational Spectra and Conformation of the Thiooxalic Acid Derivatives CH3S-CO-CONH2, CH3S-CS-CONH2, C2H50-C0-CSNH2 and K[OSC-CONH2]  
 Abstract    The crystal structures ofCH3S-CO-CONH2 (1), CH3S-CS-CONH2 (2), C2H50-C0-CSNH2 (3) and K[OSC-CONH2] (4) have been determined by single crystal X-ray diffraction. The molecules 1, 2 and 3 are nearly planar and form centrosymmetric dimers by N H • • • O or N-H--S hydrogen bonds with the amidic oxygen or sulfur atom as acceptor atoms. The anion of 4 is not quite planar. The torsional angle around the C-C bond is 18.4°. The con-formations of the title compounds are E, Z' (1 and 2), Z, Z' (3) and Z (4). According to the vibrational spectra, which are discussed briefly, 1 and 3 retain their conformation also in solution.

 Title    Zur Existenz diskreter TeCl 5 -Ionen On the Existence of Discrete TeCl s ~ Ions  
 Abstract    Discrete mononuclear TeCl 5 " anions were prepared for the first time in solid phase in associa-tion with bulky cations as tetrabutylammonium and tetraphenylphosphonium. The vibrational spectra imply tetragonal symmetry as for the isoelectronic TeF 5 ~ anion which is caused by a stereochemically active lone pair. A complete vibrational assignment is given and supported by a normal coordinate treatment for both ions. The significance of the resulting force constants is briefly discussed.

 Title    Strukturen und Schwingungsspektren neuer Wolframatophosphate Structures and Vibrational Spectra of Novel Tungstophosphates  
 Abstract    A solution of Na 2 W0 4 • 2 H 2 0 and Na 2 HP0 4 (3:1) was acidified with acetic and perchloric acid, respectively, and yielded mixtures of crystals. These were mechanically separated under a micro-scope according to the appearance of the crystals and the pure phases were subjected to vibrational (IR and Ra) and X-ray investigations. The compounds have the formulae Na 2n P 6 W 18 0 79 -«H 2 0 (I) with n = 41,32 and 12, and Na 12 P 4 W 14 0 5g -42H 2 0 (II), respectively. By carrying out secondary reactions one obtains two more phases of (II) with less water of crystallization (36 and 34 H 2 0) as well as a hydrolysis product of (I), the compound Na 2 0P 5 W 18 O 7 5(OH) 3 -42H 2 O (III). The struc-tures of (I) (41-hydrate), (II) (36-hydrate) and (III) were discussed. Besides centrally bound phosphate groups their anions also contain peripherally bound phosphate groups. These com-pounds can now be identified by the characteristic features of their vibrational spectra.

 Abstract    Hexachlorocyclotrisiloxane (2) and octachlorocyclotetrasiloxane (4) were prepared by reac­ tion o f SiCl4 with 0 2 at 955 C. Their mass spectra are compared with those o f the isoelectronic cyclophosphazenes. The vibrational spectra o f 2 and 4 are very similar and closely related to that o f (PNC12)3, but clearly different from that o f the puckered (PNCU) 4 molecule. The X-ray examination o f 2 and 4 reveals planarity o f the (SiO)", n = 3 and 4 ring systems, with d (S i-O) on average 1.619(4) and 1.584(3) Ä, respectively.

The electronic spectra show the typical J i-jr*-transitions (B, Q, N region) of the Pc2~ ligand together with a number of extra bands due to trip-multiplett and (Pc, Br — » M)CT transitions. vs(MBr) is observed in the resonance Raman (RR) spectrum (RR enhanced for M = Fe, Ru) at 161 cm-1 (Fe), 183 cm4 (Ru) and 192 cm-1 (Os), vas(MBr) at 251 cm4 (Fe), 234 cm-1 (Ru) and 218 cm-1 (Os) in the FIR spectra. The RR spectra obtained by excitation at low absorbance between the B and Q region are dominated by the intraconfigurational 'T 7 — > r 8" transition due to spin orbit split­ ting of the 2T2g ground state for Fe at 583 cm-1, Ru at 1026/1050 cm-1 and Os at 3131 cm4 . In the MIR resp. NIR spectra vibronically induced transitions are observed for the Ru or Os complex.

 Title    Ba2Na(CN2)(CN)3, ein neues Cyanamid-cyanid mit interpenetrierenden Teilstrukturen Ba2Na(CN2)(CN)3, a Novel Cyanamide Cyanide with Interpenetrating Substructures  
 Abstract    Ba2Na(CN2)(CN)3 was obtained by the reaction of Ba2N with melamine and NaCN at 700 °C. The compound was structurally characterized by single-crystal X-ray investigations (Fd3m, a = 1518.8(3) pm, Z = 16). In the crystal structure the Ba"+ ions form a cubic close packed arrangement, the Na+ and the CN2_ ions occupy the octahedral interstices. The CN-ions are located within the close packed Ba2+ layers. The unit cell of Ba2Na(CN2)(CN)3 contains two interpenetrating substructures of the zinc-blende structure type, building up a variant of NaTl. A reversible phase transition has been observed during cooling of the compound. Whereas the Ba2(CN2)(CN)3 sublattice remains nearly unaffected in this process, the Na+ ions of the low-temperature phase are statistically distributed on two crystallographic positions.

 Title    Hexaborate Cluster Radical Anions [B6Haln Hal'^« ]*" and [B6Hal5R]*_ (Hai, Hai' = CI, Br, I; R = H, alkyl). Chemical or Electrochemical Generation, Vibrational, UV-Vis and EPR Spectroscopy  
 Abstract    Paramagnetic hexaborate clusters with mixed halide, halide/alkyl or halide/hydride substi­ tution were prepared from oxidizable dianionic precursors and were characterized by cyclic voltammetry, EPR, vibrational and UV-VIS spectroscopy. The EPR studies reveal increasing g anisotropy and EPR linewidths on replacing Cl by Br and especially by I substituents; on the other hand, the replacement of one halide by one alkyl (CH3 or CFFCN) or hydride substituent in [BftHalsR]*-causes decreasing radical persistence and g anisotropy. These results indicate a fairly uniform participation of the cluster core and the substituent sphere in the spin distribution as a major factor for the stability of these non-7r radicals.

Good agreement between experimental and calculated lattice vibration frequencies is obtained using a force field which includes short-range force constants only. This demonstrates a highly covalent bonding character of the cooperites.

The non-CO-bridged form of Co2(CO)6(C6H 5)2PCH2CH2P(C6H 5)2 gives insertion reactions with Hg, SnCl2 and CsGeCl3 yielding the probably oligo-or polymeric compounds Hg[Co(CO)3]2(C6H s)2PCH2CH2P(C6H 5)2 and Cl2M[Co(CO)3]2(C6H 5)2PCH2CH2P(C6H 8)2 (M = Sn, Ge).

 Title    Darstellung von Phthalocyaninen von Ib-Elementen in aprotischen Lösungsmitteln Preparation of Phthalocyanines of lb-Elements in Aprotic Solvents  
 Abstract    The double decomposition of (TDBA)LiPc(2-) with halocomplexes of the lb-elements is investigated in nonpolar aprotic solvents. Phthalocyanines of the formula MLiPc(2-) are isolated only for the univalent cations Cu(I) and Ag(I), but not for Au(I). The impure AgLiPc(2-) is light sensitive. In contrast to earlier observations only oxidation products of the phthalocyanine anion are obtained in the presence of Cu(II) and Au(III). The preparation of Ag(II) and Au(II) phthalocyanines failed. Abkürzungen: TBA+ = w-Tetrabutylammonium, [(C4H9)4N]+, TDBA+ = n-(Tridodecyl-butyl)ammonium, [(Cl2H25)3C4H9N]+, Pc(2-) = Phthalocyanin(2-), [C32HI6N8] 2 -, Pc(l-) = Phthalocyanin(l-),

 Title    Chemie poly funktioneller Liganden, 48 [1] Synthese, Schwingungsspektren, Molekül-und Kristallstruktur eines Organocyclotriarsan-pentacarbonylchrom-Komplexes Chemistry of Polvfunctional Ligands, 48 [1] Synthesis, Vibrational Spectra, Molecular and Crystal Structure of an Organocyclotriarsane-pentacarbonylchromium Complex  
 Abstract    The organocyclotriarsane, CH3C(CH2As)3 (1), reacts with chromium hexacarbonyl on ultraviolet irradiation to give the complex CH3C(CH2As)3Cr(CO)5 (2), in which the cyclo-triarsane is behaving as a monodentate ligand. The crystal structure of 2 has been determinated by X-ray diffraction. The monoclinic unit cell (space group P2i/n) contains 4 isolated molecules in a hexagonal closest packing. The mass spectrum of 2 shows the parent peak and clear fragmentation patterns. The infrared and Raman spectra are reported for 1 and 2 in the 3000-30 cm -1 region. Most of the fundamental vibrations are assigned.
