catena -Poly[[aquadicinnamatocadmium]--1,4-diazabicyclo[2.2.2]octane]

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.
