Abstract: The title compound, [Cd(C₉H₈O₂)₂(C₆H₁₂N₂)(H₂O)]_n, forms a one-dimensional polymeric chain. Both cinnamate ligands are bidentate anions and the 1,4-diazbicyclo[2.2.2]octane (dabco) molecule acts as an end-to-end bridging ligand. The Cd atom, located at a position of site symmetry m, has a slightly distorted pentagonal bipyramidal coordination environment consisting of two N atoms of dabco ligands, four cinnamate O atoms and one water ligand, with the dabco N atoms in the axial positions. The chains are cross-linked by hydrogen bonds involving the coordinated water molecules, forming a two-dimensional network.
