Structure regulation of Nickel (II) complexes with imidazole-tripodal ligand by altering the counter anions and the reaction conditions

摘要

. For the reaction products of N,N-bis(2-(1-methyiimidazolyl)methyl)glycine (HL) with nickel (II), the conversion from a mononuclear complex of [NiL(H2O)2]NO3·CH3OH(1) to a trinuclear complex of [NiL(H2O)2] [Ni(H2O)4(CH3O)2]2(SO4)2·(H2O)2 (2) was achieved by altering the types of the counter anions and the pH value of the reaction system. The coordination structures were studied by single-crystal X-ray analysis. The electrochemical and magnetic properties were measured to reveal the structure-property relationship.
