(R(P))-5-Methyl-2-(propan-2-yl)cyclo-hexyl phen-yl{phen-yl[(1-phenyl-eth-yl)amino]-meth-yl}phosphinate.

In the title compound, C(31)H(40)NO(2)P, the P atom has a distorted tetra-hedral stereochemistry [bond-angle range about P = 103.33 (6)-115.24 (15)°] and has R(P) chirality, which was confirmed crystallographically. The dihedral angles between the P-bonded phenyl ring and the other two phenyl rings are 40.4 (3) and 12.2 (2)°. In the crystal, a C-H⋯O inter-action links mol-ecules into chains which extend along [100].

1,2-Diphenyl-2-[(1-phenyl-eth-yl)amino]-ethanol.

In the mol-ecule of the title compound, C(22)H(23)NO, there are two chiral atoms (R* for the C atom attached to the OH group and S* for the C atom attached to the phenyl ring). In the crystal, neighbouring mol-ecules are connected into a chain along the b axis by N-H⋯O hydrogen bonds.
