Özet

New cyano-bridged heteronuclear polymeric complexes, [M(mim) 2Pd(CN)4]n (M = Cu(II) (1) or Cd(II) (2); mim = 2-methylmidazole), have been synthesized and characterized by elemental, thermal, FT-IR and Raman spectral analyses. The crystal structure of complex 1 has been determined by single crystal X-ray diffraction technique. The crystallographic analysis reveals that it crystallizes in the monoclinic system, space group P21/c. The Pd(II) atom is coordinated by four cyano ligands, while Cu(II) atom is also surrounded by the two mim and two cyano ligands. The structure of 1 is formed by infinite 2,2-TT type chains of the [-Cu(mim)2-NC-Pd(CN)2-CN-]n composition; these are interlinked by hydrogen bonds (HBs) leading to two-dimensional patterns. FT-IR and Raman spectral data indicate the presence of bridging cyano ligands in the structures of the complexes.© 2014 Elsevier B.V. All rights reserved.
