2,2'-{[2-(2-Hy-droxy-phen-yl)-4-methyl-imidazolidine-1,3-di-yl]bis-(methyl-ene)}diphenol.

The asymmetric unit in the title compound, C24H26N2O3, comprises two independent mol-ecules (A and B). In molecule A, the central 2-hydroxyphenyl ring is inclined to the mean plane of the major component of the imidazolidine ring by 84.52†(14)°, and by 68.08†(9) and 47.48†(9)° to the outer phenol rings. The later are inclined to one another by 66.76†(9)° and by 78.12†(14) and 80.20†(14)° to the imidazoline ring mean plane. In molecule B, the central 2-hydroxyphenyl ring is inclined to the mean plane of the imidazolidine ring by 73.64†(10)°, and by 75.60†(8) and 38.32†(9)° to the outer phenol rings. The later are inclined to one another by 69.47†(9)° and by 82.60†(10) and 64.26†(10)° to the imidazolidine ring mean plane. In each of the independent mol-ecules, two intra-molecular O-H⋯N hydrogen bond form S(6) ring motifs. In disordered mol-ecule A, the O-H groups of the 2-hy-droxy-benzyl groups are also involved in intra-molecular O-H⋯O hydrogen bonds, with the O atom of the hy-droxy-phenyl group acting as the acceptor. In the crystal, A molecules are linked by pairs of O-H⋯O hydrogen bonds forming inversion dimers. These dimers are linked to the B molecules via O-H⋯O hydrogen bonds forming double-layered slabs lying parallel to the bc plane.
