Synthesis, Structure, and Electrochemical Properties of Cobalt Complex Based on N-(2,5-Bis(methoxycarbonyl)phenyl)-α-diphenylphosphorylglycinate

New bis-chelate cobalt(II) complex [Co(DPG) 2 (DMF) 2 ] ( 1 ), where DPG is N -(2,5-bis(methoxycarbonyl)phenyl)-α-diphenylphosphorylglycinate, has been prepared and characterized. The complex is the first example of cobalt complex containing phosphorylated derivative of α-amino acid. Octahedral coordination geometry of the cobalt complex 1 has been determined by X-ray diffraction. Electrochemical reduction of the obtained complex has been found to be irreversible two-electron process ( = –1.70 V vs Ag/AgNO 3 , 1 × 10 –2 М in CH 3 CN), resulting in formation of cobalt metal adsorbed on the surface of working electrode.
