Poly[μ2-aqua-bis[μ4-2-(1H-1,2,3-benzotriazol-1-yl)acetato]dipotassium]

Abstract

In the title compound, [K2(C8H6N3O2)2(H2O)]n, each K+ ion is seven-coordinated by one O atom from a bridging water molecule, five carboxylate O atoms and one N atom from a benzotriazole group, forming a distorted mono-capped octahedral geometry. In the crystal, the carboxylate groups act as bridging ligands, forming a two-dimensional polymer parallel to (001). The aqua ligand, which lies on a twofold rotation axis, forms intermolecular O—H...O hydrogen bonds within these layers.
