6,6′-Dimethyl-2,2′-[imidazolidine-1,3-diylbis(methylene)] diphenol

Abstract

In the title compound, C19H24N2O 2, a di-Mannich base derived from 2-methylphenol and 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane, the imidazolidine ring adopts a twist conformation, with a twist about the ring N - C bond [C - N - C - C torsion angle = -44.34 (14)°]. The two 2-hydroxy-3-methylbenzyl groups are located in trans positions with respect to the imidazolidine fragment. The structure displays two intramolecular O - H⋯N hydrogen bonds, which each form an S(6) ring motif. In the crystal, the molecules are linked by weak C - H⋯O interactions with a bifurcated acceptor, forming a three-dimensional network.
