【Abstract】 Synthesis and crystal structure of the title compound are described. This crystal is monoclin-ic, space group P21/c with a=10. 710(2), b= 9. 114(2), c= 16. 864(3) A, β= 102. 94(1), V= 1604. 55(O) A 3 ,Z=4, Dc= 1. 99g/cm3, p=65. 20 cm-1, F(000) =919, R=0. 050, Rw=0. 050.The structure was solved by direct methods. The tin atom of the title molecule exists in adistorted-trigonal-bipyramidal geomctry defincd by two carbon, two bromide and ope oxygenatoms. Three carbon、one oxygen and onc tin atoms lcad to a fivc-mcmbcrcd chelate rjng. In thestructure, cyclohexanyl group has a chair conformation and the fivc-mcmbcrcd ring containingthe intermolecular O-Sn has a half chair con formation.更多还原
