Abstract: The crystal structure of the title compound, [Cu(C₇H₄NO₄)₂(C₆H₁₂N₂)(H₂O)]_n, contains a one-dimensional polymeric chain running along the a axis. Both p-nitrobenzoate groups are monodentate ligands and dabco (1,4-diazabicyclo[2.2.2]octane) acts as an end-to-end bridging ligand. The Cu atom has a slightly distorted square-pyramidal (SQP) coordination involving two N atoms of the dabco ligand, two O atoms from the carboxylate group of the p-nitrobenzoate anions and one water ligand. The point symmetry of the copper(II) polyhedron with the p-nitrobenzoate anion ligands is mm, these ligands lying on mirror planes. The chains are crosslinked by hydrogen bonds involving the coordinated water molecule to form layers parallel to (101).
