Abstract

A series of A-frame Pt(II) acetylide complexes [Pt₂(μ-dppm)₂(μ-C≡CR)(C≡CR) ₂]⁺ (R = C₆H₅, C₆H₄OMe-P, C₆H₄OEt-P, C₆H₄Et-p, Bp, ^tBu) have been isolated and shown to exhibit strong luminescence in both the solid state and in fluid solution. All these A-frame acetylide complexes have been found to exhibit fluxional properties. The free energies of activation for the fluxional process of selected Pt(II) A-frame acetylide complexes have been determined.
