Phosphinethiolate tin(IV)-11 group-metal derivatives. X-ray structure of [Au2Sn(tBu)2(C6F5)2(SC6H4PPh2)2]
摘要:
[SnR2Cl2] reacts with (SC6H4PPh2)(-) giving [SnR2(SC6H4PPh2)(2)] (R = Me, Bu-t, Ph) (1a-c). These compounds can displace tetrahydrothiophene from [Au(C6F5)(tht)] or [Au(tht)(2)]ClO4 or reacts with AgClO4. Complexes [SnR2{(SC6H4PPh2)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 Elsevier Science S.A. All rights reserved.

The complexes cis-[M(Ph2PC6H4-2-S)2] M=Ni, Pd, Pt were stereoselectively synthesized by transmetallation reactions of [M(Cl)2(NCC6H5)2] M=Pd, Pt or NiCl2·6H2O with [Sn(R)2(Ph2PC6H4-2-S)2] R=Ph, nBu or tBu. The conformation of the Pd and Pt derivatives being unequivocally confirmed by single crystal X-ray diffraction studies showing both metal centers to be into a slightly distorted square planar environment
