(3-Aminophenyl)diphenylphosphine oxide–2-propanol (1/1)

The title compound, C18H16NOP·C3H8O, was synthesized by the reduction of (3-nitrophenyl)diphenylphosphine oxide in the presence of 2-propanol as recrystallization solvent. There are two molecules in the asymmetric unit. Each P atom is tetracoordinated by three C and one O atom from two phenyl fragments, one aniline group and one double-bonded O atom in a distorted tetrahedral geometry. C—H...π and N—H...π interactions are present. In the crystal structure, a wide range of non-covalent interactions consisting of hydrogen bonding [of the types of O—H...O, N—H...O and C—H...O, with D...A distances ranging from 2.680 (3) to 3.478 (3) Å] and π–π [centroid–centroid distance of 3.7720 (15) Å] stacking interactions connect the various components into a supramolecular structure.
