| Abstract: Complex [Cu2L2(H2O)2]n(2) (H4L=bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxyllic acid), has been synthe-sized under hydrothermal condition and characterized by elemental analysis, IR spectra, powder X-ray diffraction and single-crystal X-ray analysis. Single crystal of compound H4L·2H2O (1) was also obtained under the hydrothermal condition. Crystal data for 1: C12H16O10, triclinic, space group P1. a=0.885 54(15) nm, b=0.955 66(16) nm, c=1.043 88(17) nm, α=110.863(3)°, β=91.127(3)°, γ=91.429(3)°, V=0.824 9(2) nm3, Z=2, Mr=320.25, Dc=1.289 g·cm-3, F(000)=336, μ=0.115, the final R=0.064 8 and wR2=0.180 2 for observed reflections 1 940 with I>2σ(I). Crystal data for 2: C6H6CuO5, Orthorhombic, space group Pnnm. a=2.766 8(6) nm, b=0.638 75(14) nm, c=0.737 32(16) nm, V=1.303 1(5) nm3, Z=4, Mr=442.31, Dc=2.254 g·cm-3, F(000)=884, μ=3.324, the final R=0.059 4 and wR=0.191 7 for observed reflections 1 247 with I>2σ(I). The structural analysis show that the complex 1 is zero-dimensional structures and hydrogen bonds result in three-dimensional supramolecular structures. The complex 2 is a three-dimensional network structures. CCDC: 766358, 1; 752937, 2. |
