Syntheses, IR spectra, thermal properties and crystal structures of novel cyano-bridged polymeric complexes of zincII and cadmiumII with tetracyanoplatinateII (original) (raw)

Two novel one-dimensional polymeric cyano-bridged platinum(II) complexes of N-(2-hydroxyethyl)-ethylenediamine (hydeten), [M II (hydeten)Pt(CN) 2 (l-CN) 2 ] n (M II = Zn II (1) and Cd II (2)), were synthesized and characterized by physico-chemical methods (elemental analysis, IR spectroscopy and thermoanalytical measurements) and X-ray diffraction. Thermal behaviours of 1 and 2 were followed using TG and DTA (DSC) techniques. The 1D chain structures of 1 and 2 were verified by X-ray diffraction studies. According to the positions of the bridging cyano groups, in complex 1 the polymeric chains are built up via the 2,2-CT type, while in complex 2 the polymeric chains are built up via the 2,2-TT type.
