Abstract: The title compound [systematic name: 1,2;3,4-di--chloro-1,4-dichloro-1,1,2,2,3,3,4,4-octaphenyl-di-₃-oxo-tetratin(IV)], [Sn₄(C₆H₅)₈Cl₄O₂], crystallizes as a CH₂Cl₂ solvate. Unlike the previously known unsolvated form, the structure does not possess a crystallographic inversion center. The dimer consists of a central Sn₂O₂ ring with two additional adjacent Sn₂ClO four-membered rings. The Sn, O and Cl atoms are approximately coplanar; the Sn atoms exhibit a distorted trigonal-bipyramidal configuration.
