Poly[μ5-{hydrogen bis-[(E)-cinnamato]}-caesium].
In the structure of the title polymeric complex, [Cs(C9H7O2)(C9H8O2)] n , a caesium salt of trans-cinnamic acid, the Cs(+) ions of the two individual irregular CsO8 coordination 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 inter-linked 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.
