Abstract

Reaction of the unsymmetrically-bridged di-iridium(I) complex [(cod)Ir(μ-pz)(μ-fpz)Ir(cod)], [cod = cyclo-octa-1,5-diene; pzH = pyrazole; fpzH = 3,5-bis(trifluoromethyl)pyrazole] with hexafluorobut-2-yne (C₄F₆) leads to bridge-replacement of μ-fpz by C ₄F₆; the latter is incorporated in a parallel-type bonding mode to give a di-iridium product having Ir-Ir 2.85 Å and one Ir centre terminally co-ordinated by a 1-3,5,6-η-C₈H₁₁ (i.e. -dienyl) unit.
