title: (E)-2-[(2-Amino-phen-yl)imino-meth-yl]-4,6-di-tert-butyl-phenol.
abstract: In the title compound, C(21)H(28)N(2)O, the dihedral angle between the rings is 35.2 (2)°. A weak intra-molecular O-H⋯N hydrogen bond is observed between the O-H H atom and the imine N atom. In the crystal, mol-ecules are linked by additional inter-molecular N-H⋯O hydrogen bonding, resulting in a wave-like chain along the b-axis direction.
