Abstract
The new complex [H2Met][Zn(dipic)2]·3H2O (1) (dipicH2=2,6-pyridinedicarboxylic acid) and Met=metformin (N,N-dimethylebiguanidine), was synthesized and characterized by elemental analysis, FTIR, 1H NMR, 13C NMR and UV–Vis spectroscopy and single crystal X-ray method. The crystal system is triclinic with space group Pī. The unit cell dimensions for ZnII complex is a=9.3817(5), b=10.0714(5), c=12.4917(6). In this complex, metformin is diprotonated and acts as counter ion. The intra and intermolecular hydrogen bonds stabilize the crystal structure of compound. The redox behavior of the complex was investigated by cyclic voltammetry.
