title: Poly[μ-aqua-bis-(μ5-2,4-di-chloro-benzoato)dipotassium].
abstract: In the title compound, [K2(C7H3Cl2O2)2(H2O)] n , the potassium salt of 2,4-di-chloro-benzoic acid, the repeating unit in the polymeric structure consists of two identical irregular KO6Cl units related by twofold rotational symmetry, linked by a bridging water mol-ecule lying on the twofold axis. The coordination polyhedron about the K(+) ion comprises a carboxyl-ate O atom and a Cl-atom donor from a bidentate chelate ligand inter-action, four O-atom donors from a doubly bridging bidentate carboxyl-ate O,O'-chelate inter-action and the water mol-ecule. A two-dimensional polymeric structure lying parallel to (100) is generated through a series of conjoined cyclic bridges between K(+) ions and is stabilized by water-carboxyl-ate O-H⋯O hydrogen-bonding inter-actions.
