Schiff base complex of gallium trichloride:synthesis and crystal structure

A new Schiff base complex of gallium trichloride(C_(13)H_(10)ClNO·GaCl_3) was synthesized by the reaction of gallium trichloride and N-salicylidene-m-chloroaniline under argon atmosphere.The complex was characterized by elemental analysis,1H 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=90(A),β=90(A),γ=90(A),V=1605.4(5)(A)3,Z=4,F(000)=808,R_1=0.0283,ωR_2=0.0649.In this complex,the Ga center is four-coordinate with distorted tetrahedron geometry.And Intermolecular hydrogen bonds link the molecules of the complex into 2-D network.CCDC:649106.
