Their structure were characterized by elementary analysis, IR and 1H NMR and the crystal structure were determined by X-ray single crystal diffraction. The crystal of complex 1 belongs to orthorhombic with space group Pccn, a=2.096 1(12) nm, b=1.018 5(6) nm, c=1.205 9(7) nm, Z=4, V=2.574(2) nm3, Dc=1.624 g·cm-3, μ(MoKα)=1.348 mm-1, F(000)=1 272,R1=0.038 7, wR2=0.088 5. The crystal of complex 2 belongs to monoclinic with space group C2/c, a=1.531 3(16), b=1.868 4(19), c=0.951 8(10) nm, β=112.602(14)°, Z=4, V=2.514(5) nm3, Dc=1.612 g·cm-3, μ(MoKα)=1.572 mm-1, R1=0.025 4, wR2=0.070 4. In the complexes 1 and 2, the structures consist of discrete molecules containing six-coordinate tin atom in a distorted octahedron configuration.
