Syntheses, spectroscopic and thermal analyses of the hofmann-type metal(II) tetra- cyanonickelate(II) pyridazine complexes: {[M(pdz)Ni(CN)4]∙H2O}n (M = Zn(II) or Cd(II))

“…Analogous shifts on coordination were observed in pyridine [5], 4,4'-bipridyl [20] and 2-methylpyrazine [11,12] complexes. These shifts were explained as the coupling of the internal modes of the aromatic molecule with the M-N vibrations [5,[20][21][22]. The C-H stretching bands of pdz were observed in the 3100-3000 cm -1 region.…”
