	Title	Darstellung, Kristallstruktur und Infrarotspektrum von [MONC13 * P0C13]4 Preparation, Crystal Structure and Infrared Spectrum of [MONC13 * P0C13]4
	Abstract	[MoNCl3 • P0C13]4 is prepared both by the reaction of MoNCl3 with POCl3 as well as by the reaction of M0CI5 with NC13 in the presence of P0C13. [MONC13 • P0C13]4 crystallizes in the monoclinic space group P2i/c with 2 tetrameric molecules in the unit cell. The crystal structure was solved by X-ray diffraction methods (R — 0.033, 1821 observed reflections). The structure consists of planar and almost square Mo4N4-eight-membered rings with alternating Mo-N bond lengths. The distorted octahedral environment of the molybdenum atoms is completed by three terminal Cl-ligands and by the oxygen atom of a POCl3 molecule, which is coordinated trans to the Mo = N triple bond. The IR spectrum is discussed with respect to the vibrational spectra of the isoelectronic niobium complex [NbOCl3 • P0C13]4.

	Abstract	The first two examples of a novel series of organo-actinide complexes, [CpsUXL] (Cp = r/ 5 -CoH5, X = halide or pseudohalide anion, L = uncharged Lewis base), are described. The X-ray structure analysis of the system with X = NCS and L = CH3CN confirms an almost linear alignment (H3)CCNUNCS along with the coplanarity of the three Cp ring normals. The remarkable Lewis acidity of certain CpsUX-compounds appears to be essential for the formation of oligomeric species [Cp3UX]oo as well as for specific reactions of monomeric CP3UX.

	Title	a Novel Conformation of the NPPh3 Group
	Abstract	The X-ray crystal structure of heptachloro-(triphenylphosphazenyl)cyclotetraphosphaza-tetraene N4P4Cl7(NPPh3) reveals a novel con-formation (tending to Type III) of the tri-phenylphosphazenyl group with respect to the adjacent ring segment. This observation is contrasted with the structure of N3P3Cl5(NPPh3) where a Type I conformation is observed.

	Title	Crystallisation Processes in Metal Rich Rubidium Oxides
	Abstract	On the basis of X-ray investigations a structural model for the orientational disorder of Rbg02 clusters in the rubidium suboxide RbeO is derived, which is in accordance with details of the thermal analysis of the ordering process. In the second part the thermal and structural investigations of a metastable phase of the probable composition Rbe,330 are described. The phase is formed by warming quenched samples Rb;rO (9 >x > 7) to co. 140 K and decomposes at ca. 183 K. Its cubic structure bears relationships to the structure of rubidium as well as to YBe6 (replacing B12 icosahedra in the latter compound by Rb atoms). A special DTA instrument used for the investigation of Rbe.330 is described.

	Abstract	A simple, quick and reliable method is derived to calculate values of [(0,F)/Me] for block structures. The method of calculation is exemplified using ideal and real (defect) block structures and inconsistent published data. The method represents a simple means to systematically classify block structures.

	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.

	Title	Eine neuartige Assoziation zwischen Kalium und komplex gebundenem DistickstofF -Struktur von KN2Co(PMe3)3 A Novel Association of Potassium and Co-ordinated Dinitrogen - Crystal Structure of KN2Co(PMe3)3
	Abstract	[(Me3P)3CoN2]2Mg(THF)4 reacts with potassium metal to give [KN2Co(PMe3)3]6. The same compound is obtained via substitution of olefin in cobaltates K + [Co(olefin)(PMe3)3] _ by molecular nitrogen under ambient conditions. Infrared data show that association is preserved even in ether solvents. The stability of cobaltates [Co(PMe3)3L]~ increases in the order L — olefin < dinitrogen < PMe3. Reactions of the title compound proceed as oxidative additions to the monomer with loss of molecular nitrogen. Methyl iodide and allyl bromide yield the fluxional complexes CoCH3(PMe3)4 and ^ 3 -C3H5Co(PMe3)3, respectively. Ethyl bromide gives cis-CoH(C2H4)(PMe3)3 via /3-elimination and coordination of ethylene. The molecular structure of [KN2Co(PMe3)3]6 reveals a novel type of cluster: a double cube made up from six KN2 units with six aro-Co(PMe3)3 groups (d(NN) = 116-118 pm, d(CoN) = 170-171 pm).

	Abstract	Besides the well-known argyrodite (AggGeSß), the new compound Ag2GeS3 could be synthesized from Ag2S-GeS2 mixtures. Ag2GeS3 crystallizes in an orthorhombic variant of the Wurtzite structure. Treatment of Ag2GeS3 in a Agl/AgCl-eutectic yields the quaternary compound Ag7GeSsI. Crystal data for AgyGeSsI and some analogous compounds are given.

	Title	Cyclische Diazastannylene, II 1 Intermolekulare Lewis-Säure-Base-Addukte bei 1.3.2.4A 2 -Diazasilastannetidinen Cyclic Diazastannylenes, II 1 Intermolecular Lewis-Acid-Base Adducts of 1, 3,2,4A 2 -Diazasilastannetidines
	Abstract	-diazasilastannetidines can be prepared as mono-mers (organyl = <erf-butyl) or dimers (organyl = isopropyl) in nonpolar solvents, depending on the organic nitrogen substituent. The formation of the dimer, which is due to an intermolecular Lewis-acid-base interaction of Sn(II) with nitrogen, can be initiated by solidification. When the tertf-butyl compound is cooled below 0 °C two crystalline modi-fications are found: a monoclinic phase (C 2/c; a= 10.655(5); b = 24.75(1); c = 17.334(9) Ä; ß = 106.9(1)°) and a triclinic phase (P I; a = 10.68(1); b = 13.51(1); c = 12.36(1) A; a = 96.2(1); ß = 102.6(1); y = 118.4(1)°). The crystal structures turn out to be built of dimeric and monomeric units in the first case and presumably only dimeric species in the second case. The isopropyl derivative crystallizes in the space group P 2i/b (a = 10.77(1); b= 12.14(2); c = 11.15(2) A; ß = 120.2(2)°) with only dimeric units being present, as in the liquid. Interrelationships between the three structures are discussed.

	Abstract	Bromo-Elpasolites of formulae Cs2LiMBr6 and Cs2NaMBr6 (M = Sc, Y, La-Lu, In, V, Cr) were prepared and investigated by powder X-ray diffraction. The compounds Cs2NaMBr6 (M = Ce-Lu, Sc, Y, In) as well as Cs2LiMBr6 (M = La-Er, Y) crystallize cubic face-centered (elpasolite type of structure); Cs2NaLaBr6 and low temperature forms of Cs2NaMBr6 (M = Ce-Gd) are tetragonal. Several hexagonal crystal structure types (HT-K2LiAlF6, Cs2NaCrF6, Cs2LiGaF6) are observed for Cs2LiMBr6 (M = Tm, Yb, Lu, Sc, In, V, Cr).
