摘要
Two-dimensional network Cu(Ⅱ) compound [Cu(HGS).H2O].H2O was synthesized and characterized by elemental analysis,IR spectrum,where GS is the schiff base N-N-3-carboxy salicylidene glycine.Its crystal structrue was determined by single crystal X-ray diffraction techniques.Crystal data are as fullows: monoclinic,space group a=0.84846(3) nm,b=0.68154(3)nm,c=1.96716(8)nm,α=90°,β=95.8210(10°),γ=90°,Z=4,Dc=1.883Mg/m3,Mr=320.74,μ=1.961,F(000)=652,R=0.0279,wR2=0.0722.The copper atom is five-coordinated in a distorted square pyramidal,by one N donor,two oxygen donors,and an exogenous water forming the bottom of the square-pyramidal,with an O atom of the adjacent molecule occupying the apical site.Crystal structure indicated that the complex has two-dimensional stacking network structrue,which is formed by intramolecular hydrogen bonds,intermolecular hydrogen bonds and stacking effect of aromatic ring.
Two- dimensional network Cu（Ⅱ）compound [ Cu（HGS）· H2O]· H2O was synthesized and characterized by elemental analysis, IR spectrum, where GS is the schiff base N - N - 3 - carboxy salicylidene glycine. Its crystal structrue was determined by single crystal X - ray diffraction techniques. Crystal data are as fullows： monoclinic,space group a =0. 84846（3） nm,b =0. 68154（3） nm,c = 1. 96716（8）nm,α = 90°,β =95. 8210 （10°） ,γ =90° ,Z =4,Dc = 1. 883Mg/m^3 ,Mr =320. 74 ,μ = 1. 961 ,F（000） = 652,R =0. 0279,wR2 =0. 0722. The copper atom is five - coordinated in a distorted square pyramidal, by one N donor , two oxygen donors, and an exogenous water forming the bottom of the square - pyramidal, with an O atom of the adjacent molecule occupying the apical site. Crystal structure indicated that the complex has two -dimensional stacking network structrue ,which is formed by intramolecular hydrogen bonds, intermolecular hydrogen bonds and stacking effect of aromatic ring.
