	Title	Preparation and Crystal Structure of the Carbides Ln12Re5C15 (Ln = Y, L a-N d, G d-E r)
	Abstract	The title compounds were prepared by arc-melting of the elem ental components and sub sequent annealing. Their crystal structure is hexagonal P 6 2 m with one formula unit per cell. It was determined from single-crystal X-ray data o f La12R e5C i5 (a = 1116.8(1) pm. c = 545.3(1) pm. R = 0.060 for 287 structure factors and 27 variable parameters) and H o 12R e5C i5 (a = 1066.7(1) pm, c -504.2(1) pm, R = 0.018 for 392 F's and 31 variables). The structures correspond to the formula Ln12[ReC 3]2[R e3C3(C2)3], where the brackets indicate two differ ent trigonal planar anionic rhenium-carbon groups. The coordination of the rhenium atoms in these polyanions seem s to be compatible with the 18-electron rule.

	Title	Ein neues Carbonat mit Baylissit-Struktur: Rb2[M g(C 03)2(H 20 )4] A New Carbonate with Baylissite Structure: Rb2 [Mg(C0 3 )2(H 2 0 )4]
	Abstract	The new complex carbonate Rb2[M g (C 0 3)2(HoC))4] crystallizes in the Baylissite-tvpe structure with a = 1130,4(3), b = 641,9(1), c = 703,3(2) pm, ß = 99,62(1)°, V EZ = 503,2(2), space group P2l/n (No. 14) and Z = 2. In comparison with the isostructural potassium compound the cell dimensions increase in b-and c-and decrease in ö-direction. This effect depends on the greater coordination number of Rb+ and the rigidity of strong hydrogen bonds. The carbonate anion exhibits significant deviations from D 3h-symmetry (C -O : 127,1(5)-130,2(5) pm, Z_ O -C -O : 117.9(4)-121,1(3)°).

	Title
	Abstract	The crystal structure determination of the new rhodium(III)-complex [(DM L)(C5Me5)ClRh](PF6). DML = 1,3-dimethyllumazine, reveals 0 4,N5 coordination of the metal to DML with not very different bond lengths of 213.0(2) pm (R h -N) and 219.2(2) pm (R h -O). This result stands in contrast to the previously reported structure of a cationic dihydrobiopterin bound to [Mo(0)C13] which exhibited a very unsymmetrical chelate ar rangement. Chemical and electrochemical two-electron reduction of the Rh(III) complex led to a very labile Rh(I) species (DM L)(C5Me5)Rh which is distinguished by an intense charge transfer band in the visible. The results confirm the characterization of DML as a weak o donor In acceptor ligand with a rather low-lying tc* orbital.

	Title	Polysulfonylamine
	Abstract	, LIV [1] (12-Krone-4)lithiumdimesylamid-Acetonitril (3/2): Ein Kristall mit zwei prinzipiell unterschiedlichen Konformationen des gleichen Coronanden Polysulfonylam ines, L IV [1] (12-Crow n-4)lithium D im esylam ide-A cetonitrile (3/2): A Crystal w ith Two F undam entally D ifferent C onform ations of the Sam e C oronand A rm an d Blaschette*, K arl-H einz N agel, P e te r G. [Li(12-crown-4){N(S02CH3)2}] is obtained from equimolar amounts of lithium dimesyl amide and 12-crown-4 in methanol and crystallizes from acetonitrile as a 3/2 solvate. The crystallographic data of the latter at -130 °C are: monoclinic, space group P 2In, a = 1053.4(3), b = 904.3(3), c = 2791.2(8) pm, ß = 95.66(3)°, V = 2.646 nm3, Z = 6, Dx = 1.441 Mgm~3. Apart from CH3CN molecules residing in lattice cavities, the structure consists of two crystallogra-phically independent [Li(12-crown-4){N(S02CH3)2}] ion pairs A and B in the ratio 2:1. In B, the Li and N atoms lie on a crystallographic twofold axis. In both ion pairs, Li is hexa-coordinated by the four crown oxygen atoms O(C) and by one oxygen O(S) from each sul-fonyl group of the anionic ligand. The coordination geometry of Li in A closely resembles that of Cu11 in the known structure of [Cu(12-crown-4)Cl2] and can be pictured as a distorted octahedron, where two cis sites are occupied by the O(S) atoms and the remaining vertices by the four oxygens of the macrocycle, which displays a [4 8] conformation. The lithium atom, the two O(S) and two O(C) atoms are arranged in an approximately square-planar pattern with L i-O (S) 203.6 and 205.1, L i-O (C) 206.9 and 219.1 pm, trans angles of 173.7 and 174.8°, and cis angles in the range 87.1 -93.6°. The angle between the remaining two Li -O(C) bonds with distances 214.7 and 221.5 pm is only 146.5° compared with 180° in an ideal octahedron. In ion pair B, the coronand assumes a [3 3 3 3] conformation close to C4 symmetry, as observ ed e. g. in the known structures of [Li(12-crown-4)NCS] with a square-pyramidal 0 4N-co-ordination and [Ca(12-crown-4)(H20) 4]Cl2-4 H zO with a square-antiprismatic 0 8-geometry. The coordination polyhedron in B can be viewed as an incomplete cube in which two verti ces related by a face diagonal are unoccupied. Important bond lengths and angles in B are: L i-O (S) 216.8, L i-O (C) 214.0 and 228.7pm; 0 (S) -L i-0 (S) 82.0, 0 (C) -L i-0 (C) 75.7/76.3 for adjacent and 120.4/121.9° for opposite ring oxygens.

Synthesis and Spectroscopic Characterization o f Molecular Pentafluorophenyl Cadmium Thiolates and the Structure o f the Cubane Complex [{Cd(C6F5)(SBuf)}4]
	Abstract	In toluene, bis(pentafluorophenyl)cadmium(II) and thiols RSH (R = Bu', 2,4,6-Pr'3C6H2, 2,4,6-Bu'3C6H2) react to give soluble pentafluorophenyl cadmium thiolates [(Cd(C6F5)(SR)} J. The compounds [{Cd(C6F 5)(SBu')}4] (1)0 .5 C6H5CH3, [ {Cd(C6F5)(SC6H2Pr'3-2,4,6)} J (2)-ca. 0.25n C6H 5CH3, and [{Cd(C6F5)(SC6H2Bu'3-2,4,6)} J (3) ca. 0.25« C6H5CH3 have been prepared in 65, 59 and 78% yield, respectively. 1-0.5 C6H5CH3 crystallizes in the triclinic space group PI with a = 11,635(1)Ä, b = 11.583(1)Ä, c = 21.480(2)Ä, a = 82.12(1)°, ß = 76.26(1)°, y — 89.35(1)°, and Z = 2. 1 is a cubane-type complex with a {Cd4(/z3-SBur)4}4+ core. Each Cd atom is coordinated by three bridging thiolato ligands and one terminal C6F5 group (C d -S 2.62 A, C d -C 2.15Ä (mean values)). The central C atoms of the Bu'S" ligands of 1 show a remarkable low-field shift o f their 13C N M R resonance (12.3 ppm relative to the value of the free thiol). A characteristic spectral feature of (Cd(C6F5) } + complexes is the large value of the coupling constant 2/ (19F ,13C) o f the ipso-C atom (1, 2: 68 Hz; 3: 67 Hz). The complexes [Cd(C6F5)(SR) + H]+, [Cd(SR)2 + H]+, and [Cd2(SR)3]+ were identified in the Cl mass spectra (/50-butane) of 2 and 3.

	Title	Niedere Hydrate von Aminen. Kristallstrukturen der Hemihydrate von Ethyl-und Diethylamin sowie des Hemi-und Monohydrats von 1-Butylamin [1] Lower Hydrates of Amines. Crystal Structures of the Hemihydrates of Ethyl-and Diethylamine and the Hemi-and M onohydrate of 1-Butylamine
	Abstract	The melting diagrams of three systems alkylamine-water have been reexamined and the crystal structures of four lower hydrates determined for the first time. The hydrate EtNH2 -0.5 H20 , m.p. -72 °C, is triclinic with space^roup P 1 and Z = 4 formula units per unit cell of dimensions a = 5.104, b = 8.137, c = 9.394 Ä, a = 100.41, ß = 98.41 and y = 97.96° at -150°C. The O and N atoms are hydrogen-bonded into a two-dimensional array l[ON6/3] analogous to the layer of the Cdl2 structure type. The hydrate Et2NH • 0.5 H20 , m.p. -20 °C, is monoclinic with 12/a, Z = 8 , a -8.324, b = 15.090, c = 10.006 Ä and ß -103.34° at -100 °C. The O and N atoms are linked into a four-membered ring spiro chain ifON^] analogous to that in SiS2. The hydrate l-BuNH2 0.5H20 (m.p. -57 °C, monoclinic, P 2x/c, Z = 8,a = 14.994, b = 5.086, c = 16.15 A .,ß -103.45° at -81 °C) contains essentially the same hydrogen-bonded array as the hydrate EtNH,-0.5H20 (see above). l-BuNH2-H20 , the only monohydrate in vestigated besides the three hemihydrates (m.p. -60 °C, monoclinic, C 2/m, Z = 4, a = 9.68, b = 4.238, c = 15.58 A, ß = 94.9° at -81 °C), has also a two-dimensional H20/N H 2 partial structure, similar to a subset of the three-dimensional network of the adduct NH3 H20 of analogous composition. Z ur Bildung kristalliner Hydrate von einfachen Alkylaminen gibt es eine Reihe von z. T. schon recht frühen Untersuchungen mit allerdings nicht immer eindeutigen und widerspruchsfreien Ergebnissen. Die Bestimmung von Kristallstrukturen be schränkte sich bisher auf einige höhere Hydrate mit W assergehalten oberhalb denen von Pentahydra-ten. Solche wasserreichen Phasen wurden als Cla-thrathydrate oder Semiclathrate charakterisiert. Sie enthalten nämlich dreidimensional vernetzte W irtsstrukturen aus den W assermolekülen und in deren m ehr oder weniger gestörten polyedrischen H ohlräum en die fast immer auch noch H-brücken-aktiven (N -H — O und/oder O -H -N) Am in moleküle als Gastspezies [2]. Gegenstand der vorliegenden A rbeit sind nun erstmals K ristallstrukturen niederer Hydrate von * Sonderdruckanforderungen an Prof. Dr. D. Mootz.

	Title	Copper(II) Complexes of Hydrazone Derivatives
	Abstract	Three benzil based, macrocyclic oxygen-, nitrogen-, and sulfur-containing ligands, (3,4,10,11 -tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7,14-dithione-2,4,9,11 -tetraene) ethanol (L 1), 10,1 l-diethoxy-3,4,10,11-tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7.14-dithione-2,4-diene (L2), (3,4,10,11 -tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7.14-dione-2,4,9,l 1-tetraene) ethanol (L3); a cyclic ligand, 6-ethoxy-l,6-diphenyl-4-oxo-3,4,5,6-tetrahydro-2,3,5-triazine (L5) and two open chain ligands, benzilsemicarbazone (L6) and benzilbisthiosemicarbazone (L4) are reported. These ligands react with copper(II) chlor ide, nitrate and acetate. The complexes obtained have been characterized on the basis o f N M R , IR, electronic and mass spectral studies, conductance and analytical data. The sto-ichiometry and the spectroscopic data o f the complexes indicate that the copper ions are coor dinated by neutral ligands or by ligand anions formed by loss o f protons from the ligand. The molecular and crystal structure o f 6-ethoxy-l,6-diphenyl-4-oxo-3,4,5,6-tetrahydro-2,3,5-triazine (L 5) was determined by X-ray diffraction; the space group is triclinic, P 1 with a = 7.865(1), b = 14.101(6), c = 15.733(9) A, a = 69.10(3)°, ß = 75.62(2)°, y = 86.69(2)°, V = 1578(1) A 3, Z = 4.
