copper complex%taurine-salicylaldehyde Schiff base%crystal structure%anti- configuration
The title complex [Cu(tssb)2]·2[(H3O)Cl]·4H2O (C18H34Cl2CuN2O14S2) (tssb = taurine salicylaldehyde Schiff base) has been synthesized by the reaction of taurine salicylaldehyde Schiff base (tssb) and copper acetate in water-ethanol. Its single-crystal structure was determined by X-ray diffraction method. The crystal structure belongs to triclinic, space group P with a = 0.7407(1), b = 1.3329(3), c = 1.5736(3)nm, α = 103.800(4), β = 95.030(4), γ = 104.416(4)°, Mr = 701.06, V = 1.4433(5) nm3, Z = 2, Dc = 1.613 g/cm3, μ = 1.153 mm-1 and F(000) = 726. The compound is an infinitely expanding three-dimensional network connected with hydrogen bonds. The Cu(Ⅱ) atom is coordinated by two nitrogen and two oxygen atoms to form a distorted planar coordination compound which adopts anti-configuration because two sulfonic acid groups are positioned diagonally on a plane.
