英文摘要：

The triphenyltin 2-thiophenecarboxylate was synthesized by microwave assisted solid-state synthesis. Its structure has been determined by X-ray single crystal diffraction. The crystal belongs to monoclinic with space group P21/c, a=1.34022（6）nm,b=1.8002（6）nm,c=1.45287（6）nm,β=118.983（3）°,V=2.00994（16）nm3,Z=4,Dc=1.577g/cm2,μ（MoKa）-13.90cm^-1,F（000）-952,R1=0.0264,ωR2=0.0682.. In the complex, the tin atom has a distorted tetrahedral geometry. The study on title complex has been performed,with quantum chemistry calculation by means of G98W package and taking Lanl2dz basis set. The stabilities of the complex, the orbital energies and composition characteristics of some frontier molecular orbitals have been investigated.
