One-Dimensional Heteropolynuclear Tetracyanopalladate(II) Complexes: Syntheses, Crystal Structures, Thermal Analyses and Spectroscopic Investigations

Abstract

Three new complexes, [Ni(deten)<inf>2</inf>Pd(μ-CN)<inf>2</inf>(CN) <inf>2</inf>]<inf>n</inf> (1), [Zn(deten)<inf>2</inf>Pd(μ-CN) <inf>2</inf>(CN)<inf>2</inf>]<inf>n</inf> (2) and [Cd(deten)<inf>2</inf>Pd(μ- CN)<inf>2</inf>(CN)<inf>2</inf>]<inf>n</inf> (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<inf>1</inf>/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 C in static air. © 2013 Elsevier B.V. All rights reserved.
