Employing 4,4′-bipyridine as a bridged ligand, a new three-dimensional (3-D) hybrid zinc phosphate [Zn2(HPO4)2(4,4′-bipy)]·3H2O has been prepared under hydrothermal conditions and characterized by single crystal X-ray diffraction. This compound crystallizes in the monoclinic space group C2/c , with cell parameters, a=21.188(4)Å, b=10.229(2)Å, c=9.0656(18)Å, β=90.21(3)°β=90.21(3)°, V=1964.8(7)Å3 and Z=4Z=4. The connectivity of the ZnO3N and HPO4 tetrahedra results in a 2-D neutral layer that with interesting 4,82 net along the bc plane. Furthermore, the 4,4′-bipyridine molecule links the 4,82 net into a 3-D structure. The water molecules sit in the middle of the channels and interact with the framework via hydrogen bonds. The compound exhibits intense photoluminescence at room temperature.
