6,6'-Dimethyl-2,2'-[imidazolidine-1,3-diyl-bis(methyl-ene)]diphenol.
In the title compound, C19H24N2O2, a di-Mannich base derived from 2-methyl-phenol and 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]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-hy-droxy-3-methyl-benzyl groups are located in trans positions with respect to the imidazolidine fragment. The structure displays two intra-molecular O-H⋯N hydrogen bonds, which each form an S(6) ring motif. In the crystal, the mol-ecules are linked by weak C-H⋯O inter-actions with a bifurcated acceptor, forming a three-dimensional network.
