摘要
Reaction of Zn(ClO4)2·6H2O with septadentate 2,6-bis[bis(2-benzimidazolylme-thyl)amino methyl]-4-methylphenol (Hbbap) and sodium isonicotinate yielded a dinuclear zinc complex[Zn2(bbap) (Iso) (Hiso)] (ClO4)2·[Zn2 (bbap) (Iso) (H2O)] (ClO4)2·4H2O(1a·1b·4H2O). Hiso isisonicotinic acid and Iso is isonicotinate anion. The structure has been established by X-raycrystallography and shows that the two zinc ions are bridged by the phenoxy unit of bbap- ligand,and the presence of unusual monodentate O-coordination of carboxylate group from isonicotinicacid. The coordination geometry around the zinc ion is approximately trigonal bipyramidal.
