(E)-2'-[(3,5-Di-tert-butyl-2-hy-droxy-benzyl-idene)amino]-1,1'-binaphthalen-2-ol methanol monosolvate.
The title compound, C(35)H(35)NO(2)·CH(4)O, was obtained by the reaction of rac-2-amino-2-hy-droxy-1,1-binaphthyl and 3,5-di-tert-butyl-2-hy-droxy-benzaldehyde in absolute methanol. In the Schiff base mol-ecule, the two naphthyl bicycles are twisted by 71.15 (5)°. One hy-droxy group is involved in intra-molecular O-H⋯N hydrogen bond, while the methanol solvent mol-ecule is linked to another hy-droxy group via an inter-molecular O-H⋯O hydrogen bond.
