摘要
在无水无氧条件下,利用三氯化镓与水杨醛缩间氯苯胺反应合成了一种新的席夫碱配合物C13H10ClNO·GaCl3。利用元素分析、核磁共振、红外光谱和X射线衍射单晶结构分析对其进行了表征。单晶结构表明标题配合物晶体属于正交晶系,Pnma空间群,晶胞参数:a=17.873(3),b=7.0853(13),c=12.677(2),α=90,β=90,γ=90,V=1605.4(5)3,Z=4,F(000)=808,R1=0.0283,wR2=0.0649。该配合物中镓以四配位形式存在,形成畸变的四面体结构,配合物依靠分子间的氢键作用进一步联结成二维网状结构。
A new Schiff base complex of gallium trichloride( C13 H10ClNO· GaCl3 ) was synthesized by the reaction of gallium tri chloride and N-salicylidene-m-chloroaniline under argon atmosphere. The complex was characterized by elemental analysis,^1 NMR, IR and X-ray diffraction single crystal structure analysis. The results showed that the complex crystallizes in an orthorhombic system,the space group Pnma with a = 17. 873(3)A,b =7. 0853(13) A,c = 12. 677(2)A,α =90A, β = 90A, γ =90A, V= 1605.4 ( 5 ) A^3, Z = 4, F( 000 ) = 808,R1 = 0. 0283, wR2 = 0. 0649. In this complex, the Ga center is four-coordinate with distorted tetrahed ton geometry. And Intermolecular hydrogen bonds link the molecules of the complex into 2-D network. CCDC :649106.
