 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    Über Hydraziniumsalze von Iodoplatinaten On Hydrazinium Salts of Iodoplatinates  
 Abstract    The new compounds (N2H5)2Ptl6 and (^Hs^Ptls • H2O were obtained by reaction of H2PtCl6 with N2H5CI and HI in aqueous solutions. In the crystal structure of the ortho -rhombic bis[hydrazinium(+I)]hexaiodoplatinate(IV) (^Hs^Ptle the N2H5+ cations and Ptlö 2-anions build up a K^PtClß-like arrangement. Bis[hydrazinium(+I)]pentaiodo-platinate(II,IV)hydrate, (N2Hs)2Ptl5 • H20, is classed with the group of linear chain mixed-valence platinum complexes which have highly anisotropic properties. In the crystal structure are structurally undistinguishable Ptl4-units (Pt-I = 264 pm) connected by asymmetric I-bridges (Pt-I = 270 pm and 338 pm) to 1 [Ptl4l2/2] chains.

 Title    Isopoly-und Heteropoly-Thioanionen  
 Abstract    -und Molekülstrukturen von (PPh4)2[(WS4)WS(WS4)], CS2[(WS4)W0(WS4)H20] 2 H20 und (AsPh4)2[(WS4)Ni(WS4)] Isopoly-and Heteropoly-Thioanions. Crystal and Molecular Structures of (PPh 4)2[(WS4)WS(WS4)]. Cs2[(WS4)W0(WS4)H20] • 2 H20 and (AsPh4)2[(WS4)Ni(WS4)] The crystal and molecular structures of (PPh4)2[(WS4)WS(WS4)] (LA) and CS2[(WS4)W0(WS4)H20] • 2 H20 (2 a), which contain the first reported isopoly-thioanion of a transition metal have been determined: la: (PI, a = 913.0(1), b = 1000.1(2), c = 1333.9(2) pm, a = 87.11(1), ß = 85.18(1), v = 83.07(1)°, V = 1277.0 • 10 6 pm 3 , Z = 1); ' 2a: (P2i/n, a = 071.0(2), b = 2018.5(4), c = 714.4(2) pm, ß = 101.42(2)°, V -949,3 • 10 6 pm 3 , Z = 2) and compared with that of the trimetallic heteropoly-thioanion of (AsPh4)2[(WS4)Ni(WS4)] (3a). 3a: (PI. a = 1255.2(3), b = 1277.1(3), c = 939.0(2) pm, a = 113.19(2), ß = 90.28(2), y = 108.72(2)°, V= 1201.5-10 6 pm 3 , Z = 1). Though there are delocalized orbitals in the isopoly-thioanions they can be regarded as coordination compounds of W IV X 2+ containing two W VI S4 2 ~ ligands.
