(E)-2-{[(2-Amino-pyridin-3-yl)imino]-meth-yl}-4,6-di-tert-butyl-phenol

Abstract

In the title compound, C20H27N3O, the hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond with the imino N atom. The dihedral angle between the aromatic rings is 33.09 (9)°. In the crystal, mol-ecules form centrosymmetric dimers via pairs of N-H⋯N hydrogen bonds involving amino-pyridine fragments.
