Abstract:In the title cadmium metal-organic framework complex, [Cd(C8H3NO6)(C24H16N2)](n) or [Cd(NIPH)(dpphen)] (NIPH is nitroisophthalate and dpphen is 4,7-diphenyl-1,10-phenanthroline), the unique Cd-II cation in a general position is coordinated by four carboxy O atoms from three symmetry-related NIPH anions and two N atoms from a dpphen ligand. The Cd-II cations are bridged by pairs of NIPH anions to generate a dinuclear molecular building block, [Cd2N4(CO2R)(4)], with a Cd center dot center dot center dot Cd separation of 4.0936 (10) angstrom. Each such building block is connected to four adjacent dinuclear building blocks by NIPH anions, resulting in a two-dimensional layer framework in the bc plane. The dpphen ligands occupy the space between these layers and are linked by pi-pi interactions, with a separation of 3.4541 (6) angstrom between the central aromatic rings of inversion-related dpphen ligands. The thermogravimetric and photoluminescent properties of the complex have also been investigated.
