The title compound, C(24)H(21)N(2)OP, was obtained by reacting 2-amino-pyridine and 2-(diphenyl-phosphin-yl)benzaldehyde in ethanol. It crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The amino-pyridine units and the benzene ring bonded to the phosphine oxide P atom form dihedral angles of 88.58 (7) and 82.47 (9)° in the two mol-ecules. The crystal structure displays strong N-H⋯O and weak C-H⋯O hydrogen bonds along the b axis and C-H⋯π aromatic intra- and inter-molecular inter-actions.
