The crystal and molecular structure of a triclinic form of phosphobenzene, (PC6H5)6, referred to as B

Abstract

The triclinic form of (PC₆H₅)₆ contains two independent molecules lying on different centres of symmetry in the unit cell. The two molecules are very similar to one another and also to the molecule of (PC₆H₅)₆ in the trigonal form of this substance. The six-membered phosphorus rings in the triclinic form both have the chair configuration with phenyl groups lying in the equatorial positions.
