Complex [Zn(L)(SO4)]·0.5H2O (L= 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline) has been synthesized under hydrothermal conditions. The compound was characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21 /n with a = 9.9916(7), b = 12.3834(9), c = 29.259(2) , β = 97.7720(10)°, V = 3587.0(4)3 , Z = 2, C76H41Cl4F4N16O9S2Zn2 , Mr = 1734.91, Dc = 1.606 g/cm 3 , F(000) = 1754, μ(MoKa) = 0.959 mm -1 , R = 0.0492 and wR = 0.1385. The asymmetric unit of 1 contains one Zn(II) atom, two L ligands, one sulfate anion and half a water molecule. Each Zn(II) atom is five-coordinated by four nitrogen atoms from two different L ligands and one sulfate oxygen atom in a tetragonal pyramidal coordination environment. The N-H···O hydrogen bonds link the discrete structure of 1 into a 2D supramolecular architecture. The photoluminescent property of 1 has also been studied in the solid state at room temperature. 相似文献
