The title copper(Ⅱ) ternary complex{[Cu(C_8H_9N_2O_3S)(C_7H_6O_4)·(H_2O)_2 ]·2H_2O(1)} was synthesized by reaction of copper acetate and ligands of taurine 2-pyridinecarboxaldehyde Schiff base and 3,5-dihydroxybenzoic acid in 50% methanol aqueous solution.The structure was characterized by IR,elemental analysis and X-ray single crystal diffraction analysis.1 belongs to triclinic,space group P-1 with a=7.066(2)(A),b=11.891(4)(A),c=12.859(4)(A),α=104.034(14)°,β=96.884(13)°,γ=99.053(10)°,V=1020.9(6)(A)~3,Z=2,Dc=1.633 g·cm~(-3),μ=1.233 mm~(-1),F(000)=518,R_1=0.1108,wR_2=0.322.The central Cu(Ⅱ) is coordinated with two N and three O atoms of the ligands from taurine Schiff base,3,5-dihydroxybenzoic acid and two water molecules,leading to a square pyramidal geometry.The complexes aggregate via π┈π interaction of benzene ring and pyridine ring,and are further linked by the solvent water,coordinated water and uncoordinated sulfonate through O-H┈O hydrogen bonds into a supramolecular three-dimensional network,and the crystal structure is stabilized.
