while the dinuclear complexes [SnR3]2 (7–9) were obtained by treatment of [SnR3Cl] with potassium under toluene reflux. Complexes 2, 6·0.5toluene and 7 were structurally characterized, the latter displaying a Sn–Sn bond of 2.808(7) Å, which indicates a strong tin–tin bond with covalent character in solid state. The hexaaryldistannanes 7–9 undergo transmetallation reactions with gold(I) derivatives, such
