摘要：

A novel binuclear Cu(II) complex [Cu(paba)Cl] (pabaH = 2-(2-pyridylmethylimine)benzenesulfonic acid) has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal of the title complex crystallizes in a monoclinic system, space group P21/n, with a = 6.8165(7), b = 15.3073(16), c = 12.3795(13) , β = 95.0160(10)°, V = 1286.8(2) 3, Mr = 360.26, Dc = 1.860 g/cm3, μ = 2.074 mm-1, F(000) = 724, Z = 4, the final R = 0.0252 and wR = 0.0675 for 2395 observed reflections with I > 2σ(I). The title complex is centrosymmetric and a pair of chlorides act as μ2-bridges to link two Cu(II) ions forming a binuclear complex. Every Cu(II) ion is five-coordinated by pyridyl N, imine N and sulfonate O atoms of the tridentate paba ligand as well as two bridging Cl-, constructing the distorted square-pyramidal geometry. In the structure extensive hydrogen bonds and weak π-π stacking stabilize the solid structures, through which the complex builds its 3-dimensional supramolecular structure.
