Diethyl [(4-bromophenyl)(5-chloro-2-hydroxyanilino)methyl]phosphonate

Abstract

In the title compound, C17H20BrClNO4P, intermolecular C—H...O and N—H...O hydrogen bonds form centrosymmetric R22(10) dimers linked through O—H...O intermolecular hydrogen bonds, which form centrosymmetric R22(16) dimers. All these hydrogen bonds form chains along [010]. In addition, the crystal structure is stabilized by weak C—H...Br hydrogen bonds. The very weak intramolecular N—H...O interaction forms a five-membered ring.
