Crystal structure of diethyl [(4-nitrophenylamino)(2-hydroxyphenyl)methyl]phosphonate methanol monosolvate
Abstract
In the title compound, C17H21N2O6P·CH3OH, the planes of the 4-nitroaniline and 2-hydroxyphenyl groups form a dihedral angle of 84.04 (8)°. The P atom exhibits tetrahedral geometry involving two O-ethyl groups, a Cα atom and a double-bonded O atom. In the crystal, O—H...O, N—H...O and C—H...O hydrogen bonds link the α-aminophosphonic acid and methanol molecules into chains that propagate parallel to the a axis.
