Synthesis and Structure Characterization of Aqua-(μ2- carbonato-O,O′)-(2,2′-bipyridyl)-copper(Ⅱ) Dihydrate
Under hydrothermal conditions the reaction of cis-aconitic acid with Cu2(OH)2CO3 and bipy (bipy = 2,2'-bipy) in H2O/DMF (3:2) afforded a neutral mononuclear compound [Cu- (bipy)((2-CO3)(H2O)](2H2O, which has been structurally characterized by single-crystal X-ray diffraction analysis. The crystal belongs to triclinic, space group Pī with a = 8.3950(5), b = 8.7974(5), c = 9.4496(3)（A。）, α = 98.270(3), β = 93.014(3), γ = 100.068(3)°, V = 677.83(6) （A。）3, Dc = 1.635 g/cm3, Z = 2, C11H14CuN2O6, Mr = 333.78, μ = 1.637 mm－1, λ(MoKα) = 0.71073 （A。）, F(000) = 342, the final R = 0.0616 and wR = 0.1273 for 1621 observed reflections with I > 2σ(I). The structure of the complex contains a distorted square pyramidal core with a bipy, a carbonate anion and a water molecule coordinating to a CuⅡ atom. The dihedral angle between the two planes composed of N(1)N(2)Cu(1) and O(1)O(3)Cu(1) is 21.73(8)°. The intermolecular hydrogen bonds (O…O) are observed in the crystal structure.
