采用Ni(Ⅱ)盐和氨基甲磺酸缩3,5-二氯水杨醛席夫碱(H2L)以及1,10-邻菲咯林(phen)在甲醇和水溶液中合成了三元配合物[Ni(Ⅱ)(C8H7O4NCl2S)(Phen)(H2O)]3(1),通过元素分析、红外光谱对配合物1进行了表征,并通过X射线衍射测定了其结构。结构解析表明,配合物1属三斜晶系,空间群P墿,晶胞参数为:a=1.5640(3)nm,b=1.5650(3)nm,c=1.5650(3)nm;α=94.84(3)°,β=94.73(3)°,γ=94.80(3)°,V=3.7881(13)nm3,Z=6,Dc=1.420g.cm-3,F(000)=1602,μ=1.100mm-1,最终偏差因子(对I>2σ(I)的衍射点),R1=0.0769,ωR2=0.1306,对全部衍射点R1=0.1323,ωR2=0.1468,ω-1=[σ2(Fo)2+(0.1977P)2],P=(Fo2+2Fc2)/3。配合物1通过卤卤作用(Cl-Cl0.3574(8)nm)堆积成3D无限层状结构。
The title complex [ Ni ( II ) ( C8H7O4 NCl2 S) ( Phen ) ( H2O) ] 3 is synthesized by the reaction of nickel (II) salt and ( 3, 5-dichloro-2-hydroxybenzylideneamino ) -methanesulfonic acid ( H2 L ) and 1,10- phenanthroline in the mixture solution of water and methanol. It was characterized by IR, elemental analysis. The crystal structure is determined by X-ray diffraction method and the complex is triclinic system, space group P i and cell parameters : a = 1. 5640 (3) nm, b = 1. 5650 (3) nm, c = 1. 5650 (3) nm; α = 94.84(3)°, β = 94.73(3)°, γ = 94.80(3)°, V = 3.7881(13) nm^3, Z = 6, Dc = 1.420 g·cm^-3, F(000) = 1602,μ = 1. 100 mm^-1, R1 = 0.0769, ωR2 = 0. 1306 (Ⅰ〉2σ(Ⅰ)); R1 = 0. 1323, ωR2 = 0. 1468 (to all data), ω^1 = [σ^2(Fo)^2 + (0. 1977P)^2] , P = (Fo^2 + 2Fc^2)/3. The complex 1 was constructed a 3-D network structure by halogen- halogen interaction bonds (Cl-Cl0.3574(8) nm).
