Heteronuclear tin(IV)–silver(I) complexes with phosphinothiolate ligands. X-ray structure of [AgSn(μ-SC6H4PPh2)2Me2(PPh2Me)]CF3SO3·CH2Cl2

[SnR2(SC6H4PPh2)2] (R=Me or Ph) react with silver complexes such as [Ag(CF3SO3)(PR3)] (PR3=PPh3 and PPh2Me) to give [AgSn(μ-SC6H4PPh2)2R2(PR3)]CF3SO3 (1–4) where silver atom are coordinated to the PPh2 group of the phosphinethiolate ligand as confirmed in the X-ray crystal structure of [AgSn(μ-SC6H4PPh2)2Me2(PPh2Me)]CF3SO3·CH2Cl2 (2). Similar tin derivatives [SnR2{(SC6H4)2PPh}] (R=Me, 5; R=Ph, 6) where synthesised and reacted with [Ag(CF3SO3)(PR3)] and [Ag(CF3SO3)] to give in both cases [AgSn{μ-(C6H4)2PPh}R2]CF3SO3 (R=Me, 7; R=Ph, 8)
