Five-co-ordinate cobalt(III): crystal and molecular structure of corrole(triphenylphosphine)cobalt(III)

Abstract

An X-ray structural analysis of the title compound (I) has converged at R 0.080 based on 1 332 reflections measured by diffractometer. The cobalt atom has square pyramidal co-ordination and is 0.38 Å above the plane of the corrole ligand which is disordered in the crystal. There is an intermolecular contact of 3.0 Å from a hydrogen atom of a phenyl ring to the vacant sixth co-ordination site of the cobalt. The structure was determined by the heavy-atom method. Crystals are monoclinic, space group P2₁/n, with Z= 4, in a cell of dimensions: a = 21.432(9), b= 13.513(6), c = 10.005(5)Å, β= 95.20(2)°.
