Benzyl(methyl)phosphinic acid

Abstract

The title compound, C8H11O2P, is a phosphinic compound with a tetracoordinate pentavalent P atom. The phosphinic function plays a predominant role in the cohesion of the crystal structure, both by forming chains along the b axis via strong intermolecular O—H...O hydrogen bonds and by cross-linking these chains perpendicularly via weak intermolecular C—H...O hydrogen bonds, generating a two-dimensional network parallel to (001).
