Abstract

Two new Hofmann-type complexes in the form of {[M(pdz)Ni(CN)4]·H2O}n [where pdz = pyridazine; M = Zn(II) and M = Cd(II)] have been synthesized as a powder and their structural properties have been characterized by vibrational (FT-IR and Raman) spectroscopy, thermal and elemental analysis. The spectral and thermal analysis results suggest that these complexes are similar in structure to the Hofmann type complexes and their structures consist of polymeric layers of │M−Ni(CN)4│∞ with the pdz bound to the metal (M) atom.
