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 SnIV 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 SnIV atom at the origin.
