Bis(triorganometal) and diorganometal 1,3-dithiolates (R3M)2(C6H3XS2) (C6H5XS2 1,3-dithiobenzene (for X = H) or 1,3-dithio-4-chlorobenzene (for X = Cl); M = Sn, X = Cl, R = CH3, C6H5; M = Pb, X = H, Cl, R = CH3, C2H5, C6H5) and R2M(C6H3XS2) (R = CH3, C2H5, C6H5; M = Sn, X = Cl; M = Pb, X = H, Cl) have been prepared as the first organometal IVB derivatives of 1,3-dithiols, and investigated by vibrational. 1H NMR, and (in the case of organotin compounds) Moessbauer spectroscopy.The diorganometal derivatives are monomeric and the diorganometal derivatives dimeric in solution (37 deg C).For the latter a twelve-membered ring structure is proposed for both solution and the solid state.
