Synthesis and Crystal Structure of a New 2D O-bridged Copper(Ⅱ) Coordination Polymer Constructed from Sulfonate-derived Schiff Base
摘要:
A new chain-like coordination polymer, namely, [CuL]n (1, Na2L=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)Å, β=102.392(2)°, V=1152.0(3)Å3, C13H9CuNO4S, Mr=338.83, Dc=1.953 g/cm3, Z=4, F(000)=684, μ=2.089 mm-1, the final R=0.0376 and wR=0.0956. X-ray diffraction analyses indicate that 1 displays 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 unusual 2D coordination network. In the crystal, the components form a stable 3D supramolecular architecture by C-H…O interactions and π-stacking.
