Poly[μ5-{hydrogen bis[(E)-cinnamato]}-caesium]

Abstract

In the structure of the title polymeric complex, [Cs(C9H7O2)(C9H8O2)]n, a caesium salt oftrans-cinnamic acid, the Cs+ions of the two individual irregular CsO8coordination polyhedra lie on twofold rotation axes and are linked by four bridging carboxyl O-atom donors from two cinnamate ligand species. These two ligand components are interlinked through a delocalized H atom within a short O...H...O hydrogen bond. Structure extension gives a two-dimensional coordination polymer which lies parallel to (001). The structure was determined from a crystal twinned by non-merohedry, with a twin component ratio of approximately 1:1.
