4,6-Bis(diphenylphosphanyl)dibenzo[b,d]furan

Abstract

The asymmetric unit of the title compound, C36H 26OP2, comprises two molecules which have slightly different conformations of the phenyl ring substituents. In both molecules, the dibenzofuran unit is close to being planar, with dihedral angles of 3.20 (3) and 1.86 (2)°for the two molecules. Its planarity affects the intramolecular distances between P atoms, with P⋯P distances of 5.574 (2) and 5.485 (2) Å for the two molecules.
