Abstract

A new compound of the composition [-{Zn-di-mu-bishydeten(O)-Zn}-mu-(CN)(2)Pd(CN)(2)] (1) was obtained from the reaction of PdCl2, bishydeten [N,N'-bis(2-hydroxyethyl)ethylenediamine], KCN and ZnCl2 in water/ethanol mixture. This dimeric polymer was characterized by IR spectroscopy and elemental analysis, and its thermal properties were studied by TG and DTG. In addition, the crystal structure was determined by single-crystal X-ray analysis. IR spectroscopy pointed out the existence of both terminal and bridged cyano ligands in the complex structure. When it comes to thermal analysis, the complex followed usual decomposition mechanism in which neutral ligands are decomposed first and then anionic ligands left the structure. Single crystal X-ray analysis revealed that 1 exhibited polymeric structure. An interesting feature of this complex is that ancillary bishydeten ligand acted as a bridge just like cyano groups did. In the complex structure, dimeric Zn units, which were gathered by -O atoms of bishydeten ligands in an asymmetric fashion, were bridged by tetracyanopalladate(II) anions. 1D chain turned into 3D chains by means of intermolecular hydrogen bonds.
