• Three new cyano-bridged heteronuclear polymeric complexes were synthesized.
• The complexes are analyzed by FT-IR and Raman spectra.
• The structures of 2 and 3 were determined by X-ray single crystal diffraction method.
• The structures of the complexes consist of a 1D zigzag chain.
• The adjacent 1D layers were extended to a 3D hydrogen-bonded network.
Three new complexes, [Ni(deten)2Pd(μ-CN)2(CN)2]n (1), [Zn(deten)2Pd(μ-CN)2(CN)2]n (2) and [Cd(deten)2Pd(μ-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 P21/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.
