 Title    Synthese und Kristallstruktur von Tris-//-chlorodichloro- tetrakis(dichlorsulfan)diruthenium(II, III), eines unsymmetrisch substituierten, gemischtvalenten Ruthenium(II, III)-Komplexes mit SCl2-Liganden Synthesis and Crystal Structure o f Tris-//-chlorodichlorotetrakis(disulfane)diruthenium(II, III) - an Unsymmetrically Substituted Mixed-Valence Ruthenium(II, III) Complex with SC12 Ligands  
 Abstract    Black crystals o f Ru2S4C113 have been obtained by reaction o f Ru with SC12 in closed quartz ampoules at 125 °C. The crystal structure o f the mixed-valence ruthenium(II, III) com pound (m onoclinic, a = 8.0262(15)Ä , b = 14.9612(33)Ä , c = 32.8876(55)Ä, ß = 97.03(1)°, space group P 2,/c, Z = 4) consists o f m olecules Ru2C15(SC12)4, in which the two Ru atom s are un­ symmetrically substituted by Cl and SC12 ligands. Octahedral units o f RuC15(SC12) and RuC13(SC12) 3 are Cl bridged to binuclear complexes C12(SC12)Ru(//-C1)3Ru(SC12)3.

 Title    Clathrathydrate von Tetramethylammoniumhydroxid: Neue Phasen und Kristallstrukturen [1] C lathrate Hydrates of Tetramethylammonium Hydroxide: New Phases and Crystal Structures [1]  
 Abstract    The melting diagram o f the system tetramethylammonium hydroxide-water has been re­ investigated in the region o f 6 6 .6 7 -100 mol% H 20 , using D T A , DSC and temperature-depend-ent X-ray powder diffraction. This was done as correction and supplementation o f a previous study in the same laboratory (D. M ootz, R. Seidel, J. Incl. Phenom. 8 , 139 (1990)). The system is now considered to contain as many as eight stable hydrates, three o f them dimorphic with a low-temperature a and a high-temperature ß form. The com positions are Me4N 0 H -x H 20 with x = 2 (a and ß), 4, 4.6 (a and ß), 5 (a and ß), 6.67, 7.5, 8.75 and 10. A second 7.5-hydrate, called 7 .5 a in the previous study, is now regarded as metastable. -Structure determinations have been performed for the new phases with x = 4.6 (a), 6.67 and 8.75. The 4.6a-hydrate, transforming to 4.6ß at 32 °C, is cubic with space group Pa 3 and Z = 40 formula units per unit cell. The lattice constant is a = 21.493Ä at -1 6 0 °C. The 6.67-hydrate, melting with decom ­ position at 13 °C, is monoclinic with space group P 2 ,/w and Z = 6 . It was studied as the O-deuterated isotype with unit-cell dimensions a -11.874, b = 20.019, c = 8.272 Ä and ß = 103.84° at 3 °C. The 8.75-hydrate, melting with decom position at -3 °C, is cubic with space group 143 d, Z = 16 and a -18.38(2) Ä at -2 0 °C. The three structures, as most others o f the higher hydrates o f the system studied previously, are those o f polyhedral clathrate hydrates. For the hydrates 4 .6 a and 6.67 deviations o f the anionic, i.e. proton-deficient, new water structures from being fully four-connected are described in detail. The 8.75-hydrate is isostruc-tural with the hitherto unparalleled 9.75-hydrate o f /-butyl amine. -The phase identity and structure o f the 4.6/?-hydrate were recognized as those attributed to an erroneously assumed 5/?-phase in the previous study. 5 ß now denotes the room-temperature form o f the penta-hydrate, previously called 5 a. The present 5 a is another o f the new phases and the only one o f the system with its structure still undetermined.

 Title    N,N',N'-Trimethylethylendiamin-substituierte Phosphor(III)-Verbindungen und deren Oxidation zu Derivaten mit tetra-und pentakoordiniertem Phosphor N,N',N'-Trim ethylethylenediam ine-Substituted Phosphorus(III) Com pounds and their Oxidation to Derivatives with Four-and Five-Coordinated Phosphorus  
 Abstract    A study was made o f the intramolecular donor-acceptor interaction in N ,N',N'-trim ethyl-ethylenediamine-substituted phosphorus com pounds, involving A3-, A4-and A5-phosphorus atom s, as a function o f the nature o f the substituents at phosphorus. The reaction o f N-trim ethylsilyl-N,N',N'-trim ethylethylenediam ine (1) with (Pr'0)2PCl furnished the acyclic, trimethylethylenediamine-substituted phosphorus(III) compound 4. There is no N M R spec­ troscopic evidence for an intramolecular donor-acceptor interaction between the phosphorus atom and the nitrogen atom o f the dim ethylam ino group in 4. The oxidation o f the trivalent phosphorus atom in 4 and in the related com pound 5 by sulfur, selenium, tetrachloro-o-benzoquinone, and hexafluoroacetone led to the corresponding A4P com pounds 6 -9 and to the A5P com pounds 10 and 11. N o intramolecular donor-acceptor interaction could be detected in any o f these products. There was no reaction between 5 and elemental tellurium. The reac­ tion products were characterized by N M R spectroscopy, mass spectrometry, and by elemental analysis.

They are obtained under mild conditions in cyclo­ hexane or «-hexane solution by the reaction o f the norbornadiene precursors M (CO)4N B D with the corresponding ligands. In case o f the Ge containing ligands the dilution principle was used to improve the yields o f the mononuclear derivatives. The rate o f the N B D replacement is mainly determined by the central atom M (M o > W > Cr) and only little by R, M' or x . The new com pounds have been characterized by analytical (C, H) and spectroscopic investigations ('H, 3IP N M R , IR, MS). The ligand properties are discussed on the basis o f spectroscopic data (in particular coordination effects) and the molecular structure o f the complexes Cr(CO)4[Ph2Si(OCH 2PM e2)2] (12) and M o(CO)4[Me2G e(C H 2C H 2PM e2)2] (28) obtained by X-ray diffraction studies.

 Title    Sc5Re2C7, a Complex Carbide with C3-Units  
 Abstract    The title com pound was obtained by arc melting o f the elemental com ponents and subse­ quent annealing in a high frequency furnace. It crystallizes with the orthorhombic space group Cmmm, a = 779.26(7) pm, b = 1362.0(1) pm, c = 320.62(3) pm, V = 0.3403 nm3, Z -2. The structure was determined from single-crystal X-ray data and refined to a residual o f R = 0.021 (692 F values and 21 variables). It is closely related to the NaCl-structure. Three o f the seven carbon atom s per formula unit form linear C3-units with C -C bond lengths o f 134 pm. They are coordinated to ten Sc atom s forming bicapped quadratic prisms. Additional isolated C atoms are located in octahedral voids formed by four Sc and two Re atoms. Together with the Re atom s they form tw o-dim ensionally infinite [Re2C4"~]" polyanions. The Re atoms have highly distorted tetrahedral carbon coordination with R e -C bond lengths o f 200 and 208 pm corresponding to bond orders o f about two. This coordination seems to be compatible with the 18-electron rule. The near-neighbour coordination o f the Re atoms is assymmetric. It is suggested that this is due to the space requirements o f nonbonding electrons. Samples o f Sc5Re2C7 are sem iconducting and weakly paramagnetic.
