title: Poly[μ(2)-aqua-bis-[μ(4)-2-(1H-1,2,3-benzotriazol-1-yl)acetato]-dipotassium].
abstract: In the title compound, [K(2)(C(8)H(6)N(3)O(2))(2)(H(2)O)](n), each K(+) ion is seven-coordinated by one O atom from a bridging water mol-ecule, five carboxyl-ate O atoms and one N atom from a benzotriazole group, forming a distorted mono-capped octa-hedral geometry. In the crystal, the carboxyl-ate groups act as bridging ligands, forming a two-dimensional polymer parallel to (001). The aqua ligand, which lies on a twofold rotation axis, forms inter-molecular O-H⋯O hydrogen bonds within these layers.
