Crystal structure of 1,1′-[imidazolidine-1,3-diylbis(methylene)]bis(naphthalen-2-ol)

Abstract

The crystal structure of the title compound, C25H24N2O2, at 173 K has monoclinic (C2/c) symmetry. The molecule is located on a crystallographic twofold rotation axis with only half a molecule in the asymmetric unit. The imidazolidine ring adopts a twist conformation, with a twist about the ring C - C bond. The crystal structure shows the anticlinal disposition of the two (2-hydroxynaphthalen-1-yl) methyl substituents of the imidazolidine ring. The structure displays two intramolecular O - H⋯N hydrogen bonds, each forming an S(6) ring motif.
