(±)-trans-6,6'-Dieth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenol monohydrate.

In the title hydrate, C24H30N2O4·H2O, the organic mol-ecule adopts an E conformation with respect to the azomethine double bonds. The cyclo-hexane ring is in a chair conformation. The dihedral angle between benzene rings is 79.6 (2)°. Two intra-molecular O-H⋯N hydrogen bonds are present. In the crystal, the components are linked by O-H⋯O hydrogen bonds and weak C-H⋯π inter-actions, generating a three-dimensional supramolecular architecture.
