摘要：

Reaction of the ligand 1,3-bis(2'-benzimidazolylimino)isoindoline with manganese(II) chloride in acetonitrile/methanol leads to the novel mononuclear manganese(II) complex 1,3-bis(2'-benzimidazolylimino)isoindolinedichloro manganese(II) [Mn(bimindH)Cl-2], which has been characterized by various techniques such as elemental analysis, IR, UV-Vis, ESR spectroscopy. and X-ray diffraction. The ligand bimindH was synthesized by fusing phthalonitrile and 2-aminobenzimidazole at high temperature until ammonia evolution ceased. The catalase-like activity of the complex was tested in propionitrile, and it proved to be active in the dihydrogen peroxide dismutation. Based on kinetic studies the reaction is first-order in relation to both the complex and hydrogen peroxide. (C) 2009 Elsevier Ltd. All rights reserved.
