| Abstract: | A binuclear complex Cu2(phen)2(ip)(Hip)2]·4H2O has been synthesized by the reaction of Cu(CH3COO)2·H2O, phen(1,10-phenanthroline) and isophthalic acid (H2ip) under hydrothermal condition. Elemental analysis, IR spectra and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure. Crystal data for this complex: monoclinic, space group C2/c, a = 19.214(3), b = 10.6973(14), c = 22.567(3) (A), β = 105.081(2)°,C24H19N2O8Cu, Mr= 526.95, Z = 8, F(000) = 2160, V= 4478.6(10)(A)3, Dc = 1.563 g/cm3, μ = 1.030mm-1, -24≤h≤16, -13 ≤k≤ 13, -28≤l≤28, R = 0.0369 and wR = 0.0819 for 4615 (Rint = 1.0357)independent reflections and 3290 observed ones (I＞ 2σ(Ⅰ)). Structural analysis shows that coordination geometry of Cu(Ⅱ) is a planar square, and the title complex exhibits a 2-D framework supramolecular structure by hydrogen bonds and π-π stacking interactions. |
