Zinc(II) Complexes with Dangling Functional Organic Groups

Abstract

Abstract Zinc(II) complexes with dangling functional organic groups were synthesized by reaction of zinc acetate with a series of bifunctional p ‐substituted benzene derivatives (a combination of carboxylate, oximate, amino, β‐ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observed when the second functional group was an oxime or β‐ketoimine group. When the second group was an amine or salicylaldimine moiety, these groups were additionally coordinated. From the reaction with p ‐aminobenzoic acid, the compound [Zn 2 (OOCCH 3 )(OOC–C 6 H 4 –NH 2 ) 3 ] ∞ was crystallized. It is a three‐dimensional coordination polymer with bridging aminobenzoate ligands.
