Abstract

The rapid equilibrium between five-coordinate trigonal-bi-pyramidal [Pt(pt)(pp₃)]⁺ (pt = 1-propanethiolate, pp₃ = tris[2-(diphenylphosphino)ethyl]phosphine) and square-pyramidal [PtI(pt)(pp ₃)] with an axially coordinated I^- and dissociated terminal phosphino group was clearly observed in the presence of a large excess of I^- at low temperatures. Such a square-pyramidal intermediate is expected to be formed in the course of substitution reactions of trigonal-bipyramidal Pt(II) complexes.
