Bis{[2,6-diacetylpyridine bis(2-furoylhydrazone)(1-)]dimethyltin(IV)} trans-Tetrachlorodi-methylstannate(IV)

The structure of the title compound, [Sn(CH₃)₂(C₁₉H₁₆O₄N₅)]₂[SnCl₄(CH₃)₂], revealed the presence of two complexes. One is monocationic and consists of a heptacoordinated Sn^IV atom in a distorted pentagonal-bipyramidal geometry, with an aroylhydrazone ligand acting as a pentadentate species in the equatorial plane and two methyl groups in axial positions. The other complex is dianionic and has an hexacoordinated Sn^IV atom at the origin.
