Bonding Scheme

The infrared, Raman and n.q.r. (63Cu, 65Cu) spectra of tris(trimethylphosphine sulphide)copper(I) perchlorate, [Cu(Me3PS)3] ClO4, cyclo-tris-μ(trimethylphosphine sulphide)-tri(chlorocopper(I)), (Me3PSCuCl)3, the trimethylarsine sulphide compounds [Cu(Me3AsS)3] ClO4, (Me3AsSCuCl)n (n = an integer), and the bromo and iodo compounds (Me3PSCuBr)n, (Me3PSCuI)n have been studied with the aim of finding out more about the structure and bonding in these complexes. The infrared and Raman spectra indicate that the trimethylarsine sulphide compounds are probably isostructural with the corresponding trimethylphosphine sulphide compounds. The origin of the electric field gradient responsible for the copper nuclear quadrupole coupling in these compounds is discussed, and it is shown that the copper n.q.r. results can be explained in terms of a bonding scheme involving 3d-4s orbital mixing.

The infrared and Raman spectra of bis(N,N-dibutyldithiocarbamato)gold(111) dichloroaurate(1), [(Bu2NCS2)2AU] AuCl2, and the corresponding bromo and iodo compounds have been measured, and the anion vibrational frequencies assigned. The results are compared with those for other MX2- ions (M = Cu, Ag; X = C1, Br, I). The chlorine n.q.r. frequencies for the above-named compound, and the corresponding tetraalkylammonium salts, [R4N] AuCl2 (R = Et, Bu), have also been measured. A Townes and Dailey analysis of the results indicates an ionic character of about 68% for the Au-Cl bond in the AuCl2- ion, and a net charge of about + 0.36e on the Au atom. These results are compared with those for some related metal halide complexes.

Solid Complexes

The infrared and Raman spectra of a number of iodocuprate(I) complexes have been studied. None of the solid complexes studied appears to contain the discrete diiodocuprate(I), CuI2-, or triiododicuprate(I), Cu2I3-, ions which have previously been reported in solution studies, but bright yellow compounds which may contain the hexaiodotetracuprate(I) ion, Cu4I62-, have been prepared with methyltriphenylphosphonium and methyltriphenylarsonium cations. A structure based on a tetrahedron is proposed for the Cu4I62- ion, the copper atoms lying at the corners, and the iodine atoms bridging the copper atoms and lying along the edges of the tetrahedron. The evidence for this structure, and the information concerning the bonding in the ion obtainable from the vibrational and n.q.r. (63Cu, 65Cu, 127I) spectra are discussed.

Available data on infrared and Raman spectra of S4N4 in solid state and solutions have been verified and completed. On the basis of normal coordinate analysis an attempt has been made to define with more precision the interpretation of vibration spectra of this compound given in earlier reports.

The infrared and Raman spectra of M2[V2O2(O2)4(H2O)]·xH2O and M2[V2O2(O2)4(D2O)]·xD2O (M = N(CH3)4, Cs) were measured. In the region of the vanadium-oxygen stretching vibrations, the spectra were interpreted based on normal coordinate analysis, employing empirical correlations between the bond lengths and force constants.
