异核体

Three kinds of small molecular copper and zinc superoxide dismutase mimics were synthesized with N, N-bis (benzimidazol-2-ylmethyl) amine (N3), N, N-bis (benzimidazol-2-ylmethyl) methylamine(MN3) and N,N-bis (benzimidazol-2-ylmethyl) benzylamine(BN3) as ligands. The com-plexes were characterized by UV, IR and element analysis and the structures were proposed.

模拟铜一锌超氧化物歧化酶的活性中心，以二(2-苯并咪唑)丙烷为桥、二(2-苯并咪唑亚甲基)胺(N3)、二(2-苯并咪唑亚甲基)甲胺(MN3)及二(2-苯并咪唑亚甲基)苄胺(BN3)为配体合成了3种异双核的小分子模型化合物，并进行了紫外、红外表征及元素分析，推测了可能的结构。

With two tripodal ligands, dtma and tmpa, dtma=diethylenetriamine-N'-acetate and tmpa=tris(2-pyridyl-methylamine and a polyamine ligand, trien (=triethylenetetramine), serving as terminal ligands, we synthesized 19 species of new imidazolate -bridged Cu-Zn, Zn-Zn and Cu-Cu, and other relating compounds, in which 〓 and 〓 complexes are model compounds of Cu, Zn-SOD.
