摘 要：N, N, N′, N′-tetrakis-(2-benzimidazolylmethyl)-1, 2-ethanediamine(TBIMEDA), was prepared by reaction of ethylenediamine tetra-acetic acid disodium salt(EDTA) with 1, 2-diaminobenzene in a refluxed glycol solution, and furthermore, three allomeric complexes[(MIITBIMEDA) SO4·5H2O, M = Cd, Co, Ni] were selfassembled by solvothermal method based on reaction of this ligand with the relative sulfates respectively. These allomeric complexes were characterized by elemental analysis and IR spectroscopy and their crystal structures were determined by single crystal X-ray structural analysis. In the crystal architecture of these complexes, every metal(II) ion is chelated by one neutral TBIMEDA ligand to form an octahedral core with configuration of five heterocyclic rings (five- member ring). These cores then were linked to- gether by multi hydrogen bond interactions with sul- fate ions and water molecules to construct their 3D crystal architectures.
