x-ray Crystal Structure of a Dinuclear Zinc(Ⅱ) Complex with Unusual Two Monodentate O-coordination of Carboxylate Group of Isonicotinate
摘要:
Reaction of Zn(Cl04)2·6H2O with septadentate 2,6-bis[bis(2-benzimidazolyIme-thyl) amino methyl]-4-methylphenol(Hbbap) and sodium isonicotinate yielded a dinuclear zinc complex [Zn2(bbap) (Iso) (Hiso)] (ClO4)2·[Zn2 (bbap) (Iso) (H20)] (ClO4)2·4H20(la·lb·4H20). Hiso is isonicotinic acid and Iso is isonicotinate anion. The structure has been established by X-ray crystallography 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 isonicotinic acid. The coordination geometry around the zinc ion is approximately trigonal bipyramidal.
