摘要
A new inorganic heterocycle is obtained by reacting potassium tetraphenyldithio-imidodiphosphinate with trimethyltin and dimethyltin chlorides, in benzene. X-ray diffraction analysis reveals a spirocyclic structure with the dimethyltin moiety as the coordination centre with non-planar six-membered SnS2P2N rings. The coordination at tin is nearly perfectly octahedral, with equal Sn-S [273.3(2) and 273.7(2) pm] and P-S bonds [200.9(3) and 201.9(3) pm]. The S-Sn-S and H3C-Sn-CH3 units are co-linear.
