The title Schiff base, C(21)H(26)N(2)O(2), contains two intra-molecular O-H⋯N hydrogen bonds between the hydroxyl groups and the nearest imine N atoms, each leading to a six-membered ring. Weak C-H⋯O hydrogen bonds result in a ladder network running along the a axis. In addition, inter-molecular C-H⋯π inter-actions serve to stabilize the extended structure.
