Synthesis, crystal structure, and spectral studies of the molecular complex of [60]fullerene with chloro(triphenylphosphine)gold(I), C60 • 2[(Ph3P)AuCl]

The molecular complex C-60 . 2[(Ph3P)AuCl] (1) was synthesized. The crystal and molecular structure of 1 was established by X-ray diffraction analysis. At room temperature, the [60]fullerene molecules in complex 1 are ordered due to pi-pi interactions between C-60 and the phenyl rings of the chloro(triphenylphosphine)gold(1) molecules. The satellite structure, which accompanies the Cls photoelectron peak of complex 1, is indicative of a partial suppression of a channel of losses due to pi-->pi* transition in the phenyl ring. The IR spectral data indicate that either a charge is absent or the charge transfer to the fullerene molecule is negligible.
