 Title    Resonance Raman and Electronic Spectra of Mixed Valence Compounds with Ni(II) ---X-Ni(rV) and Ni(II)—X-Pt(IY) Chains (X = C1 or Br)  
 Abstract    The resonance Raman and electronic spectra of compounds Ni(en)2X3, Ni(dapn)2X3 etc. and of compounds [Ni(en)2Pt(en)2X2](C104)4 (where X = Cl or Br) show that these are mixed valence compounds with a metal halide chain (en = 1,2-diaminoethane, dapn = 1,2-diaminopropane).

 Title    Koordinationschemie von Liganden mit den Donatoren Phosphor und Schwefel, I Nickel(II)-Komplexe mit Phosphinomethylthioethera als Liganden Gleichgewicht zwischen planarem und tetraedrischem Nickel(II) Coordination Chemistry of Ligands with the Donors Phosphorus and Sulfur, I Nickel(II) Complexes with Phosphinomethylthioethers as Ligands A Planar-Tetrahedral Equilibrium with Nickel(II)  
 Abstract    The preparation and structural characterization of phosphinomethylthioethernickel(II) complexes of the general type [NiX2(Ph2PCH2SR)2] (X = CI, Br, I, NCS: R = Me, Ph) are reported. In all the complexes the phosphinomethylthioethers act as monodentate ligands coordinating via the phosphorus atom. The isothiocyanate complexes are diamagnetic both in solution and in the solid state and have been assigned trans-planar configuration. As shown by magnetic measurements and by electronic spectroscopy, the halo complexes exhibit a square-planar (diamagnetic) ^ distorted-tetrahedral (paramagnetic) equilibrium in solution, while in the solid state the complexes are either square-planar or distorted-tetrahedral. For the complex [NiBr2(Ph2PCH2SMe)2] both isomers have been isolated in the solid state.
