2-((Z)-{3-[(Z)-(2-Hy-droxy-5-methyl-benzyl-idene)amino]-2,2-dimethyl-prop-yl}imino-meth-yl)-4-methyl-phenol

In the title compound, C(21)H(26)N(2)O(2), the dihedral angle between the two benzene rings is 73.47 (16)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The substituted benzene rings are twisted around the central quaternary C atom in opposite directions, making a vault geometry.
