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

The title compound, C(18)H(16)NOP·C(3)H(8)O, 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.
