Synthesis, crystal structure and properties of title molecular are discribed. This crystal is monoclinic, belonging to space group P2~1 with a=0.9255(3)nm, b=1.0504(3)nm, c=1.0217(3)nm, β=100.99(2)°, V=0.9750nm^3, Z=2, D~c=1.790g/cm^3, R=0.025. The structure was solved by direct method. The tin atom of the title molecule exists in a distorted-trigonal-bipyramidal geometry, defined by three carbon, one iodine and one oxygen atoms leading to a five-membered chelate ring. The X-ray analysis show that the title compound has the properties of substitution reaction with halogen rather than addition reaction.
