摘要

The copper(II) and zinc(II) complexes of N,N-bis(benzimidazole-2-ylmethyl) amine (L) have been prepared and the crystal structure of [ZnLCl2]. MeOH determined. The complex is five-coordinate with a distorted square pyramidal geometry on zinc.:Two pyridine nitrogen donors from the imidazole groups, the secondary amino group and one chloride act as in-plane donors with the axial site occupied by chloride. The zinc(II) lies some 0.65 Angstrom above the basal plane. The stepwise protonation constants of the ligand have been obtained, log K-11 = 5.638(3) and log K-12 = 10.12(1) and the stability constants (log beta(1mh)) for the copper(II) and zinc(II) complexes determined using 50% MeOH-H2O as solvent. The hydroxoaqua complexes [ML(OH) (OH2)](+) show only slight catalytic activity in the hydrolysis of the phosphotriester 2,4-dinitrophenyl diethyl phosphate, (C) 1998 Elsevier Science Ltd.
