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.
