Abstract

A vibrational study of the dinuclear gold ylide complexes [Au(CH₂)₂PPh₂]₂ and [Au(CH₂)₂PPh₂]₂X₂ (X = Cl, Br or I) has been undertaken by Raman spectroscopy. The non-bonding AuAu interaction in the Au^I dimer, [Au(CH₂)₂PPh₂)₂, at 64 cm⁻¹ shifts to higher wavenumber in the single-bonded Au^II halogen complexes, with bands at 162, 132 and 103 cm⁻¹ for X = Cl, Br and I, respectively, being assigned to ν(AuAu). The Au-X vibration was also identified. The general trends in AuAu and Au-X stretching vibrations with changing halogen are compared with those for other dinuclear metal-metal bonded complexes, with a metal-metal bond order of one, and with those for mononuclear gold-halogen complexes.
