Abstract: In the title compound, [Cd₂(C₈H₄O₄)₂(C₁₉H₁₂N₄O)₂]_n, each Cd atom is six-coordinated by two N atoms from the substituted phenanthroline ligand and four O atoms from three different benzene-1,3-dicarboxylate (m-BDC) ligands. Pairs of Cd atoms with two carboxylate bridges form a dimeric unit with twofold rotation symmetry, and these dimeric units are further bridged by m-BDC ligands to form a double-chain structure. Furthermore, neighbouring double-chain polymers are interdigitated, leading to a two-dimensional supramolecular structure.
