A new pentacoordinate Sn (IV) adduct was prepared from diphenyltin (IV) dichloride and the disulphoxide 2-phenyl-1,3-dithiane trans-1, trans-3-dioxide. Spectroscopic and X-ray diffraction studies showed the new compound to be a rare example of a pentacoordinate 1:1 adduct between an organometallic Sn (IV) species and a neutral ligand. In spite of being difunctional, the ligand is monodentate as a result of its peculiar geometry. Moreover, the adduct does not show any evidence of strong intermolecular interactions, forming discrete molecules.
