A new Cd(II) coordination polymer, namely, [Cd3(1,2,3-BTC)2(L)2]·2.25H2O (1, L = 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-A][1,10]phenanthroline and 1,2,3-BTC = 1,2,3-ben- zenetricarboxylate), has been synthesized under hydrothermal conditions. The compound was characterized by single-crystal X-ray diffraction. It crystallizes in triclinic, space group Pī with α = 11.650(2), b = 12.240(2), c = 19.760(4) A, α = 72.01(3), β = 77.11(3), γ = 83.48(3)°, V = 2609.4(9) A3, Z = 2, C56H31Cd3Cl2F2N8O14.25, Mr = 1489.99, Dc = 1.896 g/cm3, F(000) = 1466, μ(MoKa) = 1.401 mm^-1, R = 0.0401 and wR = 0.1104. Compound 1 shows a 1D chain structure, and the neigh- boring 1D chains of 1 are joined together by π···π interactions to result in a 2D supramolecular layer. In addition, the luminescent property of 1 has been studied in the solid state at room temperature. 展开更多

Complex [Zn(L)(SO4)]0.5H20 (L = 2-(2-chloro-6-fluorophenyl)-lH-imidazo[4,5- J][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) A, fl = 97.7720(10)°, V = 3587.0(4) A^3, Z = 2, C76H41CI4F4NI60952Zn2, Mr = 1734.91, Dc = 1.606 g/cm^3, F(000) = 1754, p(MoKa) = 0.959 mm-1, R = 0.0492 and wR = 0.1385. The asymmetric unit of 1 contains one Zn(lI) atom, two L ligands, one sulfate anion and half a water molecule. Each Zn(lI) 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. 展开更多
