Iodocuprates(I) with Isolated Chains [CU2I3]"" or 4 [C u 3I4]~ N-Methylpyridinium-triiododicuprate(I), C6H8NCu2I3, methyltriphenylphosphonium-tetra-iodotricuprate(I), (C6H5)3CH3PCu3I4 and tetrapropylammonium-tetraiodotricuprate(I), (C3H7)4NCu3I4 were obtained by reacting Cu with I2 and C6H8NI, (C6H5)3CH3PI or (C3H7)4NI in acetone. The crystal structures of these compounds are built up by the cations and isolated chains of edge or face sharing Cul4-tetrahedra: [C6H8N ]+ « [(C u I^ I ^)^ -, [(C6H5)3CH3P] + oc[(CuI1/2I2/3I1/4)2 (CuI2/3I2/4)]_ and [(C3H7)4N ]+ i[(C u I3/3I1/2)2 (CuI3/3)]~. There are very short C u -C u distances of 246.1(5) and 250.3(5) pm in (C3H7)4NCu3I4 produced by face sharing of Cul4-tetrahedra.

	Title	Die Kristallstruktur des elpasolith-verwandten Cyanokomplexes [N(CH3)4]2NaFe(CN)6 * H20 The Crystal Structure of the Elpasolite-Related Cyano Complex [N(CH3)4]2NaFe(CN)6 * H20
	Abstract	The compound [N(CH3)4]2NaFe(CN)6 • H20 crystallizes in the orthorhombic space group Pnma, Z = 4, a — 1863.9(2), b = 861.7(1), c — 1317.2(2) pm. The X-ray single crystal structure determination (2515 reflections, R — 0.04) revealed an elpasolite-related framework of slightly deformed Fe(CN)63_ octahedra, the mean distances in which are Fe —C = 194.0 and C—N = 113.9 pm. The strongly distorted octahedral N6 cavities formed by six Fe(CN)63_ units are occupied by monohydrated sodium ions, exhibiting a very short distance N a—O = 221.8(3) pm. By approach to one of the octahedral faces within their N6 environment the sodium ions obtain a distorted tetrahedral NaON3 coordination, N a—N = 2 x 238.0(3) and 241.3(3) pm. One of the compound's two tetramethylammonium ions, which are centered at mirror planes, is orientation-ally disordered. The reason for this is discussed.

	Title	Die Kristallstruktur von Tricarbonyl(2.6-di-rm-butyl-pyridin)chrom(0) bei 200 K Crystal Structure of Tricarbonyl(2,6-dwerr-butyl-pyridine)chromium(0) at 200 K
	Abstract	Based on single crystal X-ray diffraction data the crystal structure of tricarbonyl(2,6-dwm-butyl-pyridine)chromium(O) has been determined at 200 K: space group P 2,/n, Z = 4, lattice constants a = 680.6(5), b — 1383.3(10), c = 1763.0(16) pm, ß = 96.53(8)°, refinement to R" — 0.048 for 1672 independent reflections with F0 > 2 a. The chromium atom is ^ ^ -b o n d ed to the essentially planar pyridine ring (Cr—C: 219—222 pm, Cr—N: 221 pm). The CO ligands show "eclipsed" orientation with respect to the 2, 4 and 6 position of the pyridine ring. Two CO groups fit into the gaps formed by two methyl groups of the tert-butyl substituents in 2 and 6 position, respectively. The results are discussed in context with related arene and A3-phosphorine com plexes.

	Abstract	The melting diagram of the quasi-binary system NH3— HF between the limits NH4HF: and HF was redetermined. The compounds NH 3 • 4H F. NH3 • 5HF and NH3 ■ 8HF with melting points of 26. —14 (dec.) and —95 °C (dec.), respectively, were established as the stable phases.

	Abstract	R eN C l2(P M e2Ph)3 reacts as a Lewis base and with BC13 forms a nitrido bridge betw een Re and B. The resulting com plex R e(N B C l3)Cl2(PM e2Ph)3 crystallizes orthorhom bic in the space group Pn2! a with Z = 4. In the com plex each Re atom has six nearest neighbours in an almost octahedral arrangement with the NBC13 group being trans to one o f the Cl ligands. The difference betw een the two Re —Cl bond lengths (239,4 and 243,9 pm) indicates a weak trans effect o f NBC13.

	Abstract	A structural investigation on single crystals o f SF4 yielded the cubic space group F m 3m with a — 676.1(5) pm and Z = 4 and from this cubic close packing and at least sixfold disorder o f isolated m olecules. In one o f the experim ents of manipulating SF4 unintentional hydrolysis o f the com pound in a Duran-glass vacuum line occurred. The products SiF4 and SO F2 could be characterized by structure analysis after a miniature zone-m elting separation and crystal growth in one and the sam e thin-w alled capillary. The results for SiF4 [143m, a = 547.6(1) pm , Z = 2 at —117 °C] confirm earlier work with a higher numerical accuracy. SO F2 crystallizes in the m onoclinic space group P 2j/c with a = 524.7(1), b = 704.9(2), c = 1449.3(4) pm , ß = 97.20(2)° at -1 3 7 °C and Z = 8. Isolated molecules o f pyramidal geom etry are arranged in strongly folded layers with interm olecular S ---0 contacts.

	Abstract	The liquidus and solidus lines of the quasi binary system CF3C O O H —H20 were determined by low temperature difference thermal analysis and the resulting phase relations controlled by X-ray powder diffraction. Formation of a monohydrate and a tetrahydrate, melting congruently at —43 and —16 °C, respectively, is confirmed. In addition a metastable form of the monohydrate and a low temperature form of the tetrahydrate, stable below —47 °C, are indicated. The crystal struc tures of the stable high temperature forms were determined. From these the monohydrate (tetra gonal, space group I42d, Z = 16) is a true acid hydrate, C F ,C 0 0 H H 20 . and the tetrahydrate (triclinic, P I, Z -2) a hydrated oxonium salt, (H 50 2) + [H(CF3COO)2]~ • 6 H:0 .

	Title	Darstellung und Kristallstruktur von Tl4TiS4, TI4SnS4 und Tl4TiSe4 Preparation and Crystal Structure of Tl4TiS4, Tl4SnS4, and Tl4TiSe4
	Abstract	The isostructural com pounds Tl4TiS4, Tl4SnS4 and Tl4TiSe4 crystallize in the m onoclinic system , space group P2[/c with a — 8.328, b = 8.191, c — 15.248 Ä , ß = 104.53°; a = 8.395, b — 8.280, c — 15.398 Ä , ß = 103.69°, and a = 8.517, b = 8.389, c = 15.672 Ä , ß = 103.50°, respectively. There are four formula units in the unit cell. The crystal structures were determ ined and refined from single crystal diffractom eter data. They are characterized by isolated tetrahedral thioanions which are connected with each other by T l+ ions. The mean bond lengths are T i—S = 2.26 Ä , S n —S = 2.40 Ä and Ti —Se = 2.38 Ä . The T1 atoms are surrounded by six and seven chalcogen atom s, respectively, in an irregular and polar arrangement, thus indicating stereochem ical activity o f the lone electron pair o f the T l+ ions. T l -S distances vary from 2.93 to 3.98 Ä , T l—Se distances from 3.03 to 3.96 Ä . The Tl atom s have nearest Tl neighbours at distances ranging from 3.46 to 3.65 Ä . The crystal structure can be described as built from pseudotetragonal slabs oriented parallel to (001) which contain the cations and the tetrahedral anions. It is shown that a similar description is valid also for the crystal structures o f Tl4G eS4 [1] and N a4SnS4 [2, 3].

	Title	Salze der 1.2-Hydrazin-bis(dithiocarbonsäure): Darstellung, Schwingungsspektren und Struktur Preparation, V ibrational Spectra and Structure of Alkahm etal Salts of the l,2-H ydrazine-bis(dithiocarboxylic Acid)
	Abstract	The following salts of the l,2-hydrazine-bis(dithiocarboxylic acid) have been prepared: Mi[S->CNH —NHCS^], M = N a, K and M3[S->CN-NHCS2], M — Na, K. In the solvated crystals K2 1S2C N H -N H C S 2 '] • 4 C H 3O H (a = 718.0(5), b = 1329.3(8), c = 937.7(9) pm , ß = 109.26(6)°, space group C2/m , Z = 2) the [S2C N H -N H C S 2]2" ion possesses crystallographic C2h sym metry, i.e. a trans planar structure with a N -N bond length of 139.2(3) pm. V ibrational spectra indicate a lower sym metrical anion in the unsolvated crystals. In the trianion [S2CN —N HCS2]3_ the C —N stretching vibrations are observed at 1400 and 1310 cm" 1.

	Abstract	Die Molekül-und Kristallstruktur von Tri-terf-butylcyclotriphosphan-pentacarbonyl-chrom(O), [(f-BuP)3Cr(CO)5] Structural Chemistry of Phosphorus-Containing Chains and Rings, IX [1] The M olecular and Crystal Structure of Tri-/m -butylcydotriphosphane-pentacarbonyl-chrom ium (0), [(r-BuP)3C r(C O)5] The structure of [(f-BuP)3C r(C O)5], C 17CrH2705P3, has been determ ined by single crystal X-ray techniques, solved by 'direct m ethods', and refined to R = 0.048, wR = 0.050 for 3657 reflections by blocked least squares. The com pound crystallizes in the space group P 2x/c with a = 1664.9 pm , b — 916.5 pm , c = 3089.8 pm, ß = 91.45° and Z = 8 formula units. The structure consists of two crystallographically independent but structurally nearly identical m ononuclear [(r-BuP)3C r(C O)5] complexes with the three-m em -bered ring (/-BuP)3 as an unidentate a-donor ligand. Com pared to the free molecule (r-BuP)3 the cyclophosphane ligand is slightly distorted on account of its coordination to the C r(C O)5-group.
