4,4′-Dichloro-2,2′-[imidazolidine-1,3-diylbis(methylene)] diphenol

Abstract

The imidazolidine ring in the title compound, C 17H 18Cl 2N 2O 2, adopts a twist conformation. The observed conformation is stabilized by two intramolecular O-H⋯N hydrogen bonds, with both N atoms acting as hydrogen-bond acceptors. The phenyl substituents are aligned at 70.0 (1) and 76.6 (1)° with respect to the best plane through the five atoms of the imidazolidine ring. Weak intermolecular C-H⋯O interactions stabilize the crystal packing.
