The crystal structures have been determined by X-ray diffraction. It belongs to monoclinic system, space group P21/n with α=1.11003(3)nm,b=1.71987(5)nm,c=1.17609(3)nm,β=100.5640(10)°,V=2.20723(10)nm^3,Z=4,Dc=1.541g·cm^-3,μ(Mo Kα)=11.81cm^-1,F(000)=1023,R1=0.0268,wR2=0.0619. The tin atom is rendered five-coordination in a distorted tigonal bipyram idal- structure. The study on the title complex has been performed with quantum chemistry calculation. The stabilities, the orbital energies and composition characteristics of some frontier molecular orbitals of the complex have been investigated. The photolumineseent property of complexes was investigated. CCDC: 934721.
