cis-Dibromo-trans-dimethyl-cis-bis(N,N-dimethylacetamide)tin(IV)

The synthesis and X-ray structure analysis of the title compound, [SnBr2(CH 3)(2)(C4H9NO)(2)], are described. The crystal contains molecules which are separated by normal van der Waals distances. Organotin(IV) compounds are fo und in a variety of structural types, in which the Sn atom can, for example , be hexacoordinated. In this case, the preferred solid-state molecular str ucture of the central atom is octahedral. The degree of distortion and the configuration depend on the ligands.
