Abstract
Protonation of [Pt2(µ-R2PCH2PR2)3(PPh3)n](n= 0, R = Ph or Et; n= 1, R = Me; n= 2, R = EtO) with NH4[PF6] gives the diplatinum(I) complex [Pt2H(η1-dppm)(µ-dppm)2]+, (2), when R = Ph (dppm = Ph2PCH2PPh2), but the diplatinum(II) complexes [Pt2H2(µ-R2PCH2PR2)3]2+, in structural forms (3), R = EtO, or (4), R = Me, Et, when the substituents on phosphorus are smaller; the structure of (4), R = Et, has been determined crystallographically.Keywords
