The methyl-substituted imidazolidine ring of the title compound, C24H26N2O2, adopts an envelope conformation with the N atom adjacent to the methyl­ene group as the flap. The meth­yl–ethyl­ene fragment in this ring is disordered over two positions with an occupancy ratio of 0.899 (4):0.101 (4). The hy­droxy­benzyl groups are inclined at 71.57 (15) and 69.97 (19)° to the mean plane of major disorder component of the heterocyclic ring with an inter­planar angle between the two hy­droxy­benzyl groups of 66.00 (5)°. The phenyl substit­uent approaches a nearly perpendicular orientation relative to the mean plane of the imidazolidine ring, making a dihedral angle of 75.60 (12)°. This conformation is stabilized by two intra­molecular O—H⋯N bonds, which generate S(6) ring motifs.

Comment top

We have recently synthesized for the first time a series of tetrasubstituted imidazolidines by the reaction of N,N'-dibenzylpropane-1,2-diamine with substituted benzaldehydes, and we have provided evidence that they display intramolecular O—H···N hydrogen bonds (Rivera et al., 2013). In this article, we further advance these investigations by presenting the crystal structure of the title compound.

In the title compound, C24H26N2O2, the methyl-substituted imidazolidine ring exhibits molecular disorder over two orientations, with a refined occupancy ratio of 0.899 (4):0.101 (4) for atoms (C26, C27, C28):(C26', C27', C28'). For the major component, the imidazolidine ring (N9/C10/N11/C26/C27) adopts an envelope conformation with atom N11 as the flap: puckering parameters (Cremer & Pople, 1975) being Q2 = 0.4429 (19) Å and Φ = 75.0 (2)°. The bond lengths (Allen et al., 1987) and angles are close to standard values. Within the imidazolidine ring, bond distances and angles are comparable to those found in related structures (Rivera et al., 2012a,b). The C2—O1 and C18—O19 bond lengths are 1.374 (2) and 1.369 (2) Å, respectively, which are comparable to other C—O bond lengths in di-Mannich bases reported by us (Rivera et al., 2012a,b). The hydroxybenzyl groups makes an angle of 71.57 (15)° and 69.97 (19)° with the mean plane of heterocyclic ring defined by N9,C10,C26 and C27. With reference to this plane, the phenyl ring is almost perpendicular with a dihedral angle of 75.60 (12)°. The interplanar angle between the two hydroxybenzyl groups is 66.00 (5)°.

Single-crystal X-ray diffraction analysis reveals the existence of intramolecular O—H··· N hydrogen-bonding interactions between the two N atoms of the imidazolidine ring and the hydroxyl groups in the aromatic rings with S(6) set graph motifs (Bernstein et al. 1995) (Table 1). However, the two observed intramolecular hydrogen bond distances were different (Table 1). It is then surprising to observe the difference in O···N distances between O1···N9 [O···N = 2.757 (2) Å] and O19···N11[O···N = 2.709 (2) Å], which are longer than those observed in a related structure (Rivera et al., 2012a). Because the length of hydrogen bonds depends on bond strength, these results indicated that the nitrogen atoms in the title compound are weaker hydrogen bond acceptors than the nitrogen in related structure (Rivera et al., 2012a). This fact can be explained by the presence of the aryl group at the aminal carbon, where the imidazolidine ring adopts a conformation that causes an increase in unfavorable through-space interactions between the two nitrogen lone pairs. Thus, one of the possible consequences of these structural features is the reduction in electronic density around the nitrogen atoms.

Experimental top

For the originally reported synthesis, see: Rivera et al. (2013). The title compound (I) were recrystallized from ethanol.

Refinement top

All hydrogen atoms were discernible in difference Fourier maps and could be refined to reasonable geometry. According to common practice H atoms bonded to C were kept in ideal positions with C–H = 0.96 Å while the coordinates of the H atoms bonded to O were refined freely. In both cases Uiso(H) was set to 1.2Ueq(C,O). All non-hydrogen atoms were refined using harmonic refinement. The disordered part of molecule was refined with bond lengths kept equal for both groups. The resulting occupancy ratio was 0.899 (4):0.101 (4).
