Cyclotristannathianes (4) are obtained from R2SnCl2 (1) and Na2S*9H2O or (CH3)3SiSSi(CH3)3.Analogously, hexathiatetrastannaadamantanes are prepared from RSnCl3(2) and the sulfenylating agents mentoined before.The reaction between dimesityltin dichloride (1a) and Na2S*9H2O depending on the reaction conditions yields either the corresponding dithiadistannacyclobutane (3) or cyclotristannathiane 4a.The structure of the cyclostannathianes 3, 4, and 5 are elucidated by determining the intensity ratio of geminal 119Sn-117Sn couplings.Calculated data are confirmed by experimental values.Additional proof is provided by measuring the change of intensity ratio in the 117Sn-NMR spectrum of 4c.X-ray structure determination proved for (C6F5Sn)4S6 (5g) to have the same geometry as in solution.
