Abstract
Abstract In the solid state (tetraphenyldithioimidodiphosphinato)trimethyltin(IV) consists of Me3Sn[SPPh2NPPh2S] units linked into a 1-D olymer by secondary Sn…S interactions. The coordination geometry about tin is trigonal bipyramidal trans-S2SnC3, with two sulphur atoms (belonging to different molecular units) in axial positions [ Sn (1) S (1) = 2.517(4) A and Sn (1)… S (2′) = 3.627 A ] and three methyl groups in the equatorial sites. This coordination is uncommon for organotin thio-derivatives and is now crystallographically confirmed for the first time. The compound also incorporates the first example of a bridging, rather than chelating, dithiomidodihosphinato ligand, thus generating a supramolecular structure which acts as a host for benzene molecules aligned along the b axis of the crystal.
