 Title    Zur Reaktion von Hexamethyldistannoxan und Hexamethyldistannthian mit Phosphor-oxo-bzw. -thio-halogeniden. Schwingungsspektren von (Me2PS)20 und (Me2PS)2S A bdel-Fattah Shihada  
 Abstract    M e3S n 0 2PCl2 and (M e2PS)20 are prepared from the reactions o f (M e3Sn)20 with PO C l3 (1:1) and with M e2PSCl (1 :2), respectively. The reactions of (M e3Sn)2S with M e2PSCl and with PSBr3 lead to the formation o f (M e2PS)2S and P4S9, respectively. PO C l3 reacts with (M e3Sn)2S to give unidentified products as a result o f O/S exchange. The i.r. and Raman spectra o f the solids (M e2P S)20 and (M e2PS)2S and the Raman spectra of the m olten com pounds are reported and the frequencies assigned.

 Title    Graphite Intercalation Compounds with Trimethyltin Chloride  
 Abstract    G raphite Intercalation Com pounds, Photochem istry, Trimethyltin Chloride Intercalation com pounds o f graphite with S n (C H 3) 3Cl have been prepared by U V irradiation, in the presence o f graphite, of solutions of S n (C H 3) 3Cl, S n(C H 3)4, o r of S n(C H 3) 4 + SnCl4 in CC14. M ixtures o f stage 1, stage 2, and stage 3 compounds have been obtained. T h ey were ch aracterized by X -ra y diffraction, 119Sn M össbauer spectroscopy, and by chem ical analysis. A pparently an oligom eric, anionic species is intercalated together with some solvent.

 Title    Reactions of (SCN )2 with SnX4 (X = B r, I) A utönom a, Canto B lan co, Madrid 3 4 , Spain  
 Abstract    Fro m the reaction between (S C N)2 and Snl4 a compound is formed the formula o f which is IS n (N C S)3-I2, in which I2 m olecules form charge-transfer com plexes with thiocyanate groups. IS n (N C S)3 can be isolated from this com pound. Both compounds were characterised by m eans of elem ental analyses and U V -visible, IR and 119Sn M össbauer spectra, and a polym er structure with thiocyanate bridges was deduced. The equilibrium constant was calculated for the reaction: IS n (N C S)3-I2(solid) + CS2^± IS n (N C S)3(so lid)+ I2(solution) K = 2 . 2 ± 0 . 3 x l 0 -3 mol I-1 , and it was found that the two solid com pounds form a single phase. S nBr4 forms an unstable addition com pound with (S C N)2, which decom poses even below 0 °C.

 Title    ESCA-Untersuchungen über die Ladungsverteilung und den Bindungszustand der A3-und i 3-Phosphorine ESCA-Studies of the Charge Distribution and Bonding of A3-and A^-Phosphorines  
 Abstract    The ESC A -spectroscopic exam ination of Ä3-and A:'-phosphorines supports the theory, that these compounds are to be described as arom atic com pounds and as cyclic phosphonium-ylides, respectively. C ontrary to simple electronegativity considerations, the phosphorus atom in the Ä3-phosphorines is nearly neutral and not positively charged.

 Title    Das Reduktionsverhalten von Pentacarbonylpyridin-Komplexen des Chroms, Molybdäns und Wolframs The Reduction Behaviour of Pentacarbonylpyridinechromium, -molybdenum and -tungsten Complexes

Jan u ar 1983 C arbonyl C om plexes, Electrochem istry, E S R Spectra, M olecular O rbitals, Substituent E ffects The reduction of group V IB metal pentacarbonyl com plexes and of iodom ethylates o f 4-trimethylsilyl-, 4-acetyl-and 4-cyanopyridine has been investigated. Inform ations on the dissocia­ tion o f the com plexes and on the potential and reversibility of the one-electron reduction were obtained by cyclic voltam m etry in D M F, w hereas electron spin resonance (E S R) studies of the prim ary reduction products in the 4-acetylpyridine series revealed the distribution of the unpaired electron. The results suggest that the lowest unoccupied m olecular orbital (L U M O) is a ligand cen tered ;r*-orbital in the 4-acetyl-and 4-cyanopyridine com plexes, thus confirm ing assignm ents from photochem istry. The results allow an assessment of both N -coordination and substituent effects at the heterocyclic ligand.

N aturforsch. 3 9 b , 8 1 2 -8 1 6 (1 9 8 4); received N ovem ber 15/January 17, 1984 Coordination Chem istry, Hydrazides Com plexes of arylidene salicyloyl-and benzoyl-hydrazones with the 3d metal ions, C r(III), M n (II), F e (I II), C o (II), N i(II) and C u (II), have been prepared using 2:1 ligand to m etal ion ratio. Characterization of the isolated solids was accom plished by IR and electronic sp ectra, elemental analysis, and m olar conductivity m easurem ents. It is concluded that the two Schiff bases function as neutral bidentate ligands and the com plexes form ed assume a distorted octahedral geom etry.
