 Title    Electronic and Resonance Raman Spectra of Some New Mixed-Valence Compounds of Pt and Pd with a Metal-Halide Chain  
 Abstract    The electronic and resonance Raman spectra of new mixed-valence compounds of the type M2'[M(L)X3][M(L)X5], where M' = K, NH4, M -Pt or Pd, L = NH3 or pyridine, and X = Cl, Br or I, have been studied. The single-crystal polarized reflectance spectra indicate the one-dimensional semiconductor behaviour. The polarized resonance Raman spectra confirm the —M(II)—X-M(IV)-X linear chain structure, which is in accordance with the X-ray results. The polarization of M-N bands can be explained by the Snyder's theory (1971).

 Title    Bis(?? 5 -cyclopentacüenyl)N,N-Disiibstituted Dithiocarbamato(cUoro)oxomolybdeniim(VI) Complexes  
 Abstract    Bis(?j 5 -cyclopentadienyl)N,N-disubstituted Dithiocarbamato(chloro)oxomolybdenum(VI) complexes of the type (C5H5)2MoO(S2CNR2)C1 and (CsHshMoO^CNRR'JCl where R = Me, Et, «'-Pr and R' = cyclohexyl (cyhx) have been prepared by the reaction of stoichio- metric amounts of bis(^5-cyclopentadienyl)oxomolybdenum(VI) dichloride with sodium dichio-thiocarbamates in refluxing dichloromethane. Infrared spectral studies demonstrate that in these complexes, the dithiocarbamate ligands are bidentate. Hence a coordination number of 7 may be assigned to the molybdenum(VI) atom in each case. In addition to infrared studies, electronic spectra, NMR studies, magnetic susceptibility, elemental analyses and conductance measurements have been carried out for these complexes.
