4,4'-Difluoro-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

ABSTRACT: In the title compound, C(17)H(18)F(2)N(2)O(2), the imidazolidine ring system exists in a twist conformation. The mean plane through this ring system forms dihedral angles of 80.8 (8)° and 66.2 (13)°, with the benzene rings. The dihedral angle between the benzene rings is 52.0 (14)°. Two intra-molecular O-H⋯N hydrogen bonds each generate S(6) ring motifs. In the crystal, weak C-H⋯O hydrogen bonds form dimers, which are connected by further C-H⋯O inter-actions.
