Self-assembly, electrochemistry and magnetic behaviors of cobalt complexes with featuring imidazole–tripodal ligand

The coordination chemistry of imidazole–tripodal ligand N,N-bis(2-(1-methylimidazolyl)methyl)glycine (HL) has been studied with cobalt (II). Single-crystal X-ray analysis showed that the mononuclear complex [CoLCl] (1) could further act as the charge-negative metalloligand to assemble a heptanuclear complex of Co[CoLCl]6(NO3)2 (2) through the bridge linking of carboxylato O of L and the cooperation of the central metal ions. The electrochemical and magnetic properties were explored.
