Abstract

Two new cyano-bridged two-dimensional heteronuclear complexes, [Cd(NH3)(2)(mu-ampy)Ni(mu-CN)(2)(CN)(2)](n) (1) and [Cd(H2O)(2)(mu-amPY)Pt(mu-CN)(2)(CN)(2)](n) (2) (ampy = 4-aminomethylpyridine), were synthesized and characterized by FT-IR and Raman spectroscopic, thermal (TG, DTG and DTA) and elemental analyses and single crystal X-ray diffraction techniques. They crystallize in the triclinic system and P-1 space group. The Ni(II) or Pt(II) ions are four coordinate with four cyanide-carbon atoms in a square planar geometry and the Cd(II) ion exhibits a distorted octahedral coordination by two different N-atoms from two symmetrically equivalent ampy ligands, two ammine or aqua ligands and two bridging cyano groups.The most important features of the complexes are the presence of obvious M center dot center dot center dot pi (M = Ni(II) or Pt(II)) interactions.
