trans-positions. In the anion of 21 the phenyl substituents occupy the equatorial positions of a lightly distorted trigonal bipyramid. A thorough spectroscopical investigation of the tin complexes 1–19, including X-ray structuralstudies, which were possible for complexes with R′=aryl, revealed that these complexes are monomeric with a distorted trigonal bipyramidal [SnR′2Cl3]− anion. Both aryl groups occupy equatorial
