| 摘 要： | A novel binuclear Cu(Ⅱ)complex[Cu(paba)C1](pabaH=2-(2-pyridylmethylimine)benzenesulfonic acid)has been synthesized and characterized by elemental analysis,IR andsingle-crystal X-ray diffraction.The crystal of the title complex crystallizes in a monoclinie system,space group P21/n,with a=6.8165(7),b=15.3073(16),c=12.3795(13)(A),β=95.0160(10)°,V=1286.8(2)(A)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.
