Abstract: A facile synthetic method has been used to produce the five coordinated and six coordinated Cd(II) complexes of 4′-(4-methylphenyl)-2,2′:6′,2″-terpyridine (Mephtpy), [Cd(Mephtpy)Br2] (1) and [Cd(MPhtpy)2](ClO4)2 (2). The complexes are characterized by common physical methods and structurally analyzed by single crystal X-ray diffraction. The change of coordination ability of anion influences the metal/ligand stoichiometric ratio and therefore the packing system of the final product. For example, with Br - the metal to ligand ratio was 1:1 and with ClO4 − was 1:2. The single crystal X-ray structures revealed that geometry in 1 is square-pyramidal while in 2 is distorted octahedral.
