One-dimensional heteropolynuclear tetracyanopalladate(II) complexes: Syntheses, crystal structures, thermal analyses and spectroscopic investigations

Abstract

Three new complexes, [Ni(deten)(2)Pd(mu-CN)(2)(CN)(2)](n) (1), [Zn(deten)(2)Pd(mu-CN)(2)(CN)(2)](n) (2) and [Cd(deten)(2)Pd(mu-CN)(2)(CN)(2)](n) (3) (deten = N,N-diethylethylenediamine), have been synthesized and characterized by elemental, spectral (FT-IR and Raman) and thermal analysis techniques. The crystal structures of the complexes 2 and 3 have been determined by X-ray single crystal diffraction. The crystallographic analysis reveals that they crystallize in the monoclinic system, space group P2(1)/c. The Pd(II) atom is coordinated by four cyano groups. The M(II) atom is also surrounded by the two symmetry related deten ligands and the two symmetry related N atom of cyano groups. A possible decomposition of the complexes was investigated in the temperature range 30-700 degrees C in static air. (C) 2013 Elsevier B.V. All rights reserved.
