In the title compound, C31H40NO2P, the P atom has a distorted tetrahedral stereochemistry [bond-angle range about P = 103.33 (6)–115.24 (15)°] and has RP 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 interaction links molecules into chains which extend along [100].

(RP)-O-Menthyl phenylphosphinate (280 mg, 1 mmol) was added to (N)-benzylidene-1-phenylethanamine (209 mg, 1 mmol) in a flask and the mixture was stirred for 3 h at 80 °C. After washing with petroleum ether, the resulting solid was dried and recrystallized from diethyl ether to afford the pure title product.
All H atoms were positioned with idealized geometry with C—H = 0.93–0.98 Å or N—H = 0.86 Å and with Uiso(H) = 1.2Ueq(N and C aromatic, methylene or methine) or 1.5Ueq(C methyl). The
for L-(-)-menthol [C1(R), C2(S), C5(R)] was invoked (equivalent to C30, C25, C28, respectively using the present naming scheme), giving the configuration for the other three chiral centres as P1(R), C7(R), C9(S). The was -0.06 (15) for 2164 Friedel pairs.Chiral phosphorus compounds have been widely used in both chemistry and biology (Perlikowska et al., 2004). The P-chiral title compound, C31H40NO2P, was synthesized using (RP)-O-(-)-menthyl phenylphosphinate in a reaction with the imine N-benzylidene-1-phenylethanamine and the structure is reported here. The structures of a number of the O-menthyl substituted phosphinates are known (Meng et al., 2010; Liu et al., 2011).
In this compound (Fig. 1) the P atom has a distorted tetrahedral stereochemistry [bond angle range about P1, 103.33 (6)–115.24 (15)°] and has RP
confirmed in the determination with the invoked for L-(-)-menthol [C1(R), C2(S), C5(R)] (equivalent to C30, C25, C28 respectively using the present atom numbering scheme). This also confirmed the configuration at the other two chiral centres as C7(R) and C9(S). The dihedral angles between the P-bonded phenyl ring (C16–C21) and the other two phenyl rings [C1–C6 and C10–C15] are 40.4 (3) and 12.2 (2)°, respectively.In the
there are no reasonable acceptors for the H-atom on N1 and only a single weak intermolecular methine C9—H···O(phosphinate) hydrogen-bonding interaction (Table 1) linking the molecules into chains extending along the a axial direction (Fig. 2). There are also 73 Å3 potential solvent accessible voids present in the unit cell.For general background on chiral phosphorus compounds, see: Perlikowska et al. (2004).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Chiral phosphorus compounds have been widely used in both chemistry and biology (Perlikowska et al., 2004). The P-chiral title compound, C31H40NO2P, was synthesized using (RP)-O-(-)-menthyl phenylphosphinate in a reaction with the imine N-benzylidene-1-phenylethanamine and the structure is reported here. The structures of a number of the O-menthyl substituted phosphinates are known (Meng et al., 2010; Liu et al., 2011).
In this compound (Fig. 1) the P atom has a distorted tetrahedral stereochemistry [bond angle range about P1, 103.33 (6)–115.24 (15)°] and has RP chirality, confirmed in the determination with the invoked absolute configuration for L-(-)-menthol [C1(R), C2(S), C5(R)] (equivalent to C30, C25, C28 respectively using the present atom numbering scheme). This also confirmed the configuration at the other two chiral centres as C7(R) and C9(S). The dihedral angles between the P-bonded phenyl ring (C16–C21) and the other two phenyl rings [C1–C6 and C10–C15] are 40.4 (3) and 12.2 (2)°, respectively.
In the crystal structure, there are no reasonable acceptors for the H-atom on N1 and only a single weak intermolecular methine C9—H···O(phosphinate) hydrogen-bonding interaction (Table 1) linking the molecules into chains extending along the a axial direction (Fig. 2). There are also 73 Å3 potential solvent accessible voids present in the unit cell.
