摘要：

In the title molecule, C(17)H(20)N(2)O(2), the imidazolidine ring adopts a twist conformation. The mean plane through the five atoms of the imidazolidine ring makes dihedral angles of 70.18 (4) and 74.14 (4)degrees with the planes of the two aromatic rings. The dihedral angle between the benzene rings is 53.11 (5)degrees. Both phenol -OH groups form intramolecular hydrogen bonds to the N atoms, with graph-set motif S(6). In the crystal, pairs of O-H center dot center dot center dot O hydrogen bonds link the molecules into dimers with R(4)(4)(18) ring motifs. The crystal packing is further stabilized by C-H center dot center dot center dot O and weak C-H center dot center dot center dot pi interactions.
