Syntheses, IR Spectra, Thermal Properties and Crystal Structures of Novel Cyano-Bridged Polymeric Complexes of ZnII and CdII with TetracyanoplatinateII

Abstract

Two novel one-dimensional polymeric cyano-bridged platinum(II) complexes of N-(2-hydroxyethyl)-ethylenediamine (hydeten), [MII(hydeten)Pt(CN)<inf>2</inf>(μ-CN)<inf>2</inf>]<inf>n</inf> (MII = ZnII (1) and CdII (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. © 2007 Elsevier Ltd.
