The complete molecule of the title compound, C42H36N6O2, is generated by a crystallographic twofold axis with two C atoms of the central phenyl group lying on the axis. In the independent part of the molecule, one amino group is involved in an intramolecular N—H⋯O hydrogen bond, and the two adjacent phenyl rings are twisted from the plane of the pyrazolone ring with dihedral angles of 6.82 (3) and 88.32 (6)°. The crystal packing exhibits no classical intermolecular contacts.

A quality of PMBP (1.1 g, 4 mmol) was dissolved in EtOH (50 ml), and an EtOH solution (10 ml) containing (3-(aminomethyl)phenyl)methanamine (0.3 g, 2 mmol) was added dropwise. The mixture was refluxed on a water bath for 3 h, then cooled to room temperature. Yellow block crystals were obtained by slow evaporation of the reaction mixture.
All H atoms were placed in calculated positions, with the carrier atom-H distances = 0.93 Å for aryl, 0.97 Å for methylene, 0.96 Å for the methyl and 0.86 Å for the secondary amine H atoms, and refined as riding, with the Uiso(H) = 1.5Ueq(C) for methyl groups and 1.2Ueq(C,N) for others.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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. |

For our interest in coordination chemistry of the Schiff bases derived from 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP) (Wang et al., 2005; Zhang et al., 2010), the crystal structure of the title compound was determined by X-ray diffraction analysis.
As shown in Fig.1, the molecule is generated by a crystallographic two fold axis, with atoms C20 and C22 lying on the axis. In the independent part of the molecule, the two phenyl rings (C1—C6, r.m.s. deviation = 0.0023 Å and C12—C17, r.m.s. deviation = 0.0060 Å) are slightly twisted with respect to the central pyrazolone ring (r.m.s. deviation = 0.0040 Å) making dihedral angles of 6.82 (3)° and 88.32 (6)°, respectively. The non-hydrogen atoms of the phenylenedimethylene group are situated in a fair plane (r.m.s. deviation = 0.0013 Å). The dihedral angles between this plane and the two phenyls in the PMBP moiety are 36.27 (8)° and 82.61 (6)°, respectively. The conformation of the molecule is influenced by an intramolecular hydrogen bond N3—H3A···O1 (Table 1).
