title: 2-{(1S*,2S*)-2-[(E)-(2,4-Dihy-droxy-benzyl-idene)amino]-cyclo-hex-yl}isoindoline-1,3-dione.
abstract: In the title mol-ecule, C(21)H(20)N(2)O(4), the dihedral angle between the phenol ring and the isoindole-1,3-dione mean plane is 69.79 (6)°. The cyclo-hexane ring adopts a chair conformation. Weak inter-molecular O-H⋯O and O-H⋯N inter-actions feature as part of the crystal packing.
