Trans influence of triphenylstibine: Crystal structures of cis-[PtBr2(SbPh3)2], trans-[PtBr(Ph)(SbPh3)2], [NMe4][PtBr3(SbPh3)], and cis-[PtBr2(BbPh3)(PPh3)]

The work reports the unexpected reaction of diphenyldibromo antimonates (III) with PtCl2 and cis-[PtCl2(PPh3)2]. The reaction gives triphenylstibine containing PtIIcomplexes viz. cis-[PtBr2(SbPh3)2] (1), trans-[[PtBr(Ph)(SbPh3)2] (2), [NMe4][PtBr3(SbPh3)] (3), and cis-[PtBr2(PPh3)(SbPh3)] (4). All the complexes were characterised by elemental analyses, IR, Raman, 195Pt NMR, FAB mass spectroscopy and X-ray crystallography. A plausible mechanism via the phenyl migration is proposed for the formation of these complexes. The average Pt-Br distance in 1 is 2.456(2) A, in 2 2.496 A(trans to Ph) while in 3 it is 2.476 A (trans to Sb) implying a comparable trans influence of Ph3Sb and Ph3P.
