Two new one-dimensional coordination polymers, [Cu(hmpH)(2)Pd(mu-CH)(2)(CN)(2)](n) (1) and [Cu(hmpH)(2)Pt(mu-CN)(2)(CN)(2)](n) (2), (hmpH = 2-pyridinemethanol), have been synthesized and characterized by vibrational (FT-IR and Raman) spectroscopy, single crystal X-ray diffraction, thermal and elemental analyses techniques. Single crystal X-ray diffraction analysis indicates that complexes 1 and 2 are isomorphous and isostructural, and crystallize in the triclinic system and P-1 space group. The Pd(II) or Pt(II) ions are four coordinated with four cyanide-carbon atoms in a square planar geometry. Cu(II) ion displays a distorted octahedral coordination by two N-atoms and two O-atoms of hmpH ligands, two bridging cyanide groups. In one dimensional structure of the complexes, [M(CN)(4)](2-) (M = Pd(II) or Pt(II)) anions and [Cu(hmpH)(2)](2+) cations are linked via bridging cyanide ligands. In the complexes, the presence of intramolecular C-H center dot center dot center dot M (M = Pd(II) or Pt(II)) interactions with distance values of 3.00-2.95 angstrom are established, respectively.
