Hydrothermal synthesis and crystal structure of two luminescent three-dimensional supramolecular complexes generated from mixed ligands

Two 3D metal-organic supramolecular complexes [Zn2(btec)(2, 2′-bpy)2(H2O)2] (1), [Cd2(dpa)2(phen)2(H2O)2] (2) have been prepared by hydrothermal reaction and characterized by IR and single-crystal X-ray diffraction analysis. The 3D architectures of 1 and 2 both possess rectangular cavities. Furthermore, compounds 1 and 2 both show intense photoluminescent properties at room temperature.
