Abstract

Infrared and crystallographic studies of [(CO)₄FePAr₃] complexes have been used to quantify the decreasing σ-donor/π-acceptor character of the ligand with increasing fluorine or trifluoromethyl substitution of the aryl ring. The poor coordinating ability of o-CF₃ substituted phosphines may be mimicked by o-^tBu substitution in the alkyl series.
