• Tetranuclear Cd4O4 cluster
• Tetramethyl dipyrazole
• Naphthalene tetracarboxylic acid

A coordination polymer, {[Cd-2(H(2)Me(4)bpz)(ntcaa)(2)(H2O)]center dot H2O}(n) (1), has been synthesized by hydrothermal reaction of cadmium sulfate octahydrate with a flexible ligand, 3, 3', 5, 5'-tetramethyl-4, 4'-bipyrazole and an auxiliary O-donor ligands, naphthalene-4,5-dicarboxylic acid-1,8-anhydride. Naphthalene-4,5-dicarboxylic acid-1,8-anhydride comes from the in situ dehydration of the naphthalene-1,4,5,8-tetracarboxylic acid in the hydrothermal reaction. Complex 1 exhibits a 2D wave-like layer structure based on tetranuclear Cd4O4 cluster units. The 2D wave-like layers are further held together by face-to-face pi-pi interactions between the naphthalene rings and intermolecular hydrogen bonds to generate a 3D supra-molecular network. The luminescent property of complex 1 was investigated in the solid-state at room temperature.
