[COH(NH2)2]2[Cu(pic)2(ClO4)2]的合成與晶體結構

The title compound was synthesized by reaction of Cu(ClO4)2, picolinic acid and carbamide in C2H5OH/CH3CN solution, and characterized by single-crystal X-ray diffraction. It crystallizes in the orthorhombic system,space group Pbcawith a=14.0481(8), b=9.0130(5), c=18.626(1) A, V=2358.3(2) A3, Z=4, Dx=1. 771g @ cm-3, μ= 1. 235mm-1 and F(000) = 1276. The final R factor is 0. 0440 for 1434 observed reflections.The X-ray analysis revealed that the copper (Ⅱ) atom is coordinated by two picolinic ligands in the equatorial plane,while the two oxygen atoms of perchlorate occupy the axial positions of octahedron with lengthened Cu-O distances,resulting in a 4 + 2 elongated octahedral environment. In the compound, there also exist two protonated carbamidecations for charge balance. CCDC: 195354.
