Vanadium (II) porphyrin complexes: synthesis and characterization. Crystal structure of 2,3,7,8,12,13,17,18-octaethylporphinatobis-(dimethylphenylphosphine)vanadium(II)

Abstract

The vanadium (II) porphyrins V^II(PPhMe₂)₂(porp) containing phosphine ligands have been prepared from V^II(X₂)(porp)[porp = octaethylporphinato (oep), meso-tetraphenylporphinato, meso-tetra-m-tolylporphinato, meso-tetra-p-tolylporphinato] and the crystal structure of V^II(PPhMe₂)₂(oep) has been solved by X-ray diffraction methods; the first observations of interactions between vanadium(II) porphyrins and molecular oxygen are described.
