摘要
A new Zn（II） complex, [Zn（L）（IPP）（H2O）]＇2H2O（1, H2L = 3-carboxy-l-car- boxymethyl-2-oxidopyridinium and IPP = 2-（1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl）phenol）, was synthesized under hydrothermal conditions and its structure was determined by single-crystal X-ray diffraction. It crystallizes in triclinic, space group Pi with a = 8.5023（17）, b = 9.945（2）, c = 15.573（3） A, a = 95.87（3）, β = 102.56（3）, y = 100.73（3）°, V= 1248.7（4） A3, Z= 2, C27H22N5O9Zn, Mr= 625.87, Dc = 1.665 g/cm^3, F（000） = 642, μ（MoKa） = 1.053 mm^-1, R = 0.0474 and wR = 0.1352. In 1, one L2-, one 1PP and one water molecule coordinate to the same Zn（II） atom to give a discrete complex with two lattice water molecules. Adjacent [Zn（L）（IPP）（H20）].2H20 molecules interact through π-π stacking between two IPP ligands to form a supramolecular chain. The N-H…O and O-H…N hydrogen bonds further stabilize the supramolecular chain structure of 1. The solid state luminescent property of 1 was also studied.
