Unprecedented co-ordination of a cyclo-octatetraene ligand. Synthesis and crystal and molecular structure of (η-pentamethylcyclopentadienyl)(1,4-η-octafluorocyclooctatetraene)(trimethylphosphine)rhodium(III)

Abstract

Photolysis of [Rh(η⁵-C₅Me₅)(1,2,5,6-η-C₈F₈)] in the presence of PMe₃ leads to the crystallographically characterized title compound which contains a unique example of a 1,4-η-cyclo-octatetraene ligand; this compound is an intermediate en route to formation of perfluorobicyclo[3.3.0]octadienediyl complexes.
