| 摘 要： | A new chain-like coordination polymer, namely, CuL ]n(1, Na2 L = 2-(2-hydroxybenzylidene)-amino]-benzenesulfonic acid sodium salt), has been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy and elemental analysis. Complex 1 crystallizes in monoclinic system, space group P21/c with a = 9.2296(16), b = 10.4754(18), c = 12.200(2) A, β =102.392(2)°, V = 1152.0(3) A3, C13H9 CuN O4S, Mr = 338.83, Dc = 1.953 g/cm3, Z = 4, F(000) = 684,μ = 2.089 mm-1, the final R = 0.0376 and w R = 0.0956. X-ray diffraction analyses indicate that 1displays a square-pyramidal metal center with NO4 donor sets. The sulfonate-derived Schiff base serves as a common N,O,O′-tridentate and a unique O-bridged ligand connecting the metals.Dinuclear copper complexes serve as secondary building blocks(SBUs) to construct an unusual2 D coordination network. In the crystal, the components form a stable 3D supramolecular architecture by C–H···O interactions and π-stacking.
