Özet

Three cyano bridged hetero-metallic complexes of general formula, trans-[M(N-Meim) 2Ni(μ-CN) 4] n (N-Meim=N-methylimidazole and M=Cu(II), Zn(II) or Cd(II)) have been synthesized and characterized by vibrational (FT-IR and Raman) spectroscopy, single crystal X-ray diffraction, thermal analyses and elemental analyses. The crystallographic analyses reveal that the complexes, [Cu(N-Meim) 2Ni(μ-CN) 4] n (1), [Zn(N-Meim) 2Ni(μ-CN) 4] n (2) and [Cd(N-Meim) 2Ni(μ-CN) 4] n (3), have polymeric 2D networks. In the complexes, four cyanide groups of [Ni(CN) 4] 2- coordinated to the adjacent M(II) ions and distorted octahedral geometries of complexes are completed by two nitrogen atoms of trans N-Meim ligands. Vibration assignments are given for all the observed bands and the spectral features also supported to the crystal structures of polynuclear complexes. © Springer Science+Business Media, LLC 2009.
