The novel heteronuclear compounds [Zn(hydet-en)(2)Pd(CN)(4)] (1) and [Cd(hydet-en)(2)Pd(CN)(4)] ( 2) {hydet-en: N-(2-hydroxyethyl-ethylenediamine)} have been synthesized and characterized by elemental analyses and IR spectra. The crystal structures of 1 and 2 have been determined by X-ray diffraction. Structural analysis shows that both compounds have shown a polymeric chain, in which the Zn(II)/Pd(II) and Cd(II)/Pd( II) centres are linked by two CN groups. Both zinc and cadmium atoms are six coordinate with two trans cyanide-nitrogen and four hydet-en N atoms in a distorted octahedron arrangement; the palladium atoms in 1 and 2 are four coordinate with four cyanide-C atoms in a square planar arrangement. The chains in both compounds are connected through weak interchain hydrogen bonds, N-H ... O, N-H ... N and O-H ... N, thereby forming a three-dimensional network.
