[SnR2Cl2] reacts with (SC6H4PPh2)(-) giving [SnR2(SC6H4PPh2)(2)] (R = Me, B
u-t, Ph) (1a-c). These compounds can displace tetrahydrothiophene from [Au(
C6F5)(tht)] or [Au(tht)(2)]ClO4 or reacts with AgClO4. Complexes [SnR2{(SC6
H4PPh2)Au(C6F5)}(2)] (2a-c) and [SnR2(SC6H4PPh2)(2)M]ClO4 (M = Au 3a-c; M =
Ag 4a-c) are obtained. The crystal structure of [Sn(Bu-t)(2){(SC6H4PPh2)Au
(C6F5)}(2)] (2b) has been established by X-ray diffraction. (C) 1999 Elsevi
