Abstract
Dimethylphenyltin(IV) acetate, (CH3)2(C6H5)SnOC(O)CH3, crystallizes in the orthorhombic space group Pbca with a 10.068(3), b 15.065(7), c 14.976(5) A; Z = 8; V 2271(2) A3. The structure was determined from 1793 observed out of 2348 unique reflections and refined on an R factor of 0.034. The geometry at tin is trigonal bipyramidal, with the oxygen atom of the acetate and the carbonyl oxygen of the adjacent symmetry-related (12 + x, 12 − y, 1 − z) acetate occupying the axial positions of the trans-C3SnO2 polyhedron to result in a polymer whose backbone, formed by the repetition of SnOC(O) fragment, adopts a conformation that is closer to the zig-zag configuration of trimethyltin acetate than to the helical form of triphenyltin acetate.
