(2‐Methoxy­phenyl)­phenyl­phosphine oxide

All interatomic distances in the title compound, C13H13O2P, can be considered normal. The phospho­rus tetrahedron exhibits its usual deformation. The (2-methoxy­phenyl)­phosphine section is almost planar. The structure is assembled via intermolecular C—H⋯O hydrogen bonds, to form of one-dimensional chains.
