title: rac-4-Chloro-2-[({2-[(3-chloro-6-hy-droxy-2,4-dimethyl-benz-yl)(meth-yl)amino]-prop-yl}(meth-yl)amino)-meth-yl]-3,5-dimethyl-phenol.
abstract: The title compound, C(23)H(32)Cl(2)N(2)O(2), a potential chiral ligand for coordination chemistry, was prepared by a two-step reaction. The mol-ecule is located on a crystallographic centre of inversion. As a result, the methyl group bonded to the methyl-ene group is disordered over two equally occupied positions, sharing the same site as the H atom of the chiral C atom. As a further consequence of the crystallographic centrosymmetry, the 1,2-diamino-propane unit adopts an anti-periplanar conformation and the two benzene rings are coplanar. The central chain is in an all-trans arrangement. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. A C-H⋯π inter-action links the mol-ecules into one-dimensional chains along the [001] direction.
