The compound was characterized by elemental analysis, IR, 1H NMR and MS. and the crystal structure was determined by X ray single crystal diffraction. The crystal belongs to orthorhombic with space group Pca21, a=1.8327(3)nm, b= 0.65678(12)nm, c=2.2583(4)nm, Z=4, V=2.718 (9)nm3, Dx=1.528g·cm-3,μ=1.271mm-1, F(000)=1272, R1=0.0434, wR2=0.1152. In the crystals, the structures consist of discrete molecules containing six coordinate tin atoms in a distorted octahedron configuration.展开更多
