2-[(E)-({3-[(E)-(2-Hy­droxy­benzyl­idene)amino­meth­yl]-1,4-dioxaspiro­[4.5]decan-2-yl}meth­yl)imino­meth­yl]phenol

In the title compound, C24H28N2O4, the dioxalane ring has an envelope conformation. The cyclo­hexane ring adopts a chair conformation. The dihedral angle between the benzene rings is 72.5 (3)°. The mol­ecular conformation is stabilized by two intra­molecular O—H⋯N hydrogen-bonding inter­actions with an S(6) graph-set motif. The crystal structure is stabilized by van der Waals inter­actions.
