Abstract

In this study, six new complexes (3ampyH)(2)[Ni(CN)(4)] (1), (3ampyH)(2)[Pd(CN)(4)] (2), (3ampyH)(2)[Pt(CN)(4)] (3), (4ampyH)(2)[Ni(CN)(4)] (4), (4ampyH)(2)[Pd(CN)(4)] (5) and (4ampyH)(2)[Pt(CN)(4)] (6) (3ampy = 3-aminomethylpyridine and 4ampy = 4-aminomethylpyridine) have been synthesized and characterized by spectroscopic, elemental and thermal analyses, and single crystal X-ray diffraction techniques. Complexes 1, 2 and 3 crystallize in the monoclinic system, space groups P2(1)/c, C2 and C2, respectively, whereas complexes 4, 5 and 6 crystallize in the triclinic system, space groups P (1) over bar. The asymmetric units contain one halves of the [M(CN)(4)](2) anions and the 3ampyH or the 4ampyH cations, where M is Ni(II), Pd(II) or Pt(II), respectively. The metal atoms are located on inversion centres and each metal atom is coordinated in a distorted square planar geometry by the four symmetry related C atoms from four cyano ligands.
