Abstract
The crystal and molecular structure of the title compound has been determined. Crystals are orthorhombic, space group P212121a= 19.62(1). b= 14.60(1). c= 14.55(1)Å, Z= 8, from 1 500 reflections. The data have been measured by diffractometer and the structures solved by the heavy-atom method (R 0.090). There are two independent [NMe4]+ and [Sn(O2CMe)5]– ions in the asymmetric unit, The anions contain seven-co-ordinate tin atoms in pentagonal-bipyramrdal geometry, with two bi- and one uni-dentate acetate group around the equator: Sn–O(bidentate)= 2.21 Å(mean) and Sn–O(unidentate)= 2.02 Å(mean).Keywords
