Schiff Base Complex of Gallium: Synthesis and Crystal Structure

The new Schiff base complexes of gallium GaCl3(C13H11NO) (1), GaCl3 (C14H13NO2)(2) and GaCl3(C13H9ClNO) (3) were synthesized under argon atmosphere with the glove box and characterized by elemental analysis, 1H NMR, IR, and the crystal structures were determined by single-crystal X-ray diffraction. In these complexes, the Ga center is four-coordinate with distorted tetrahedron geometry. The complex 1 crystallizes in an orthorhombic system, the space group Pnma with a=1.329 5(3) nm, b=0.701 15(16) nm, c=1.616 4(4) nm, V=1.506 8(6) nm3, Z=4, F(000)= 744,R1=0.029 5, wR2=0.065 1. And Intermolecular hydrogen bands link the molecules of the complex into two-dimensional network structure. The complex 2 crystallizes in a monoclinic system, the space group P21/n with a= 0.713 03(18) nm, b=1.715 3(4) nm, c=1.350 3(4) nm, β=91.891(5)°, V=1.650 7(7) nm3, Z=4, F(000)=808, R1=0.044 3, wR2=0.098 8. And Intermolecular hydrogen bands link the molecules of the complex into two-dimensional network structure. The complex 3 crystallizes in a triclinic system, the space group P1 with a=0.698 6(2) nm, b=1.044 9(4) nm, c=1.136 9(3) nm, α=78.58(3)°, β=81.06(2)°, γ=87.87(3)°, V=0.803 6(5) nm3, Z=2, F(000)=402, R1=0.051 5,wR2=0.1244. And Intermolecular hydrogen bands link the molecules of the complex into two-dimensional network structure.
