9,9-Dimethoxy-7,11-diphenyl-2,4-diazaspiro[5.5]undecane-1,3,5-trione monohydrate

Due to steric repulsions, the cyclo­hexane ring in the title compound, C23H24N2O5·H2O, shows some bond‐length abnormalities and adopts a chair conformation. The pyrimidine and cyclo­hexane rings are approximately perpendicular to each other, and the phenyl rings are equatorial. C—H⋯π and N—H⋯O inter...

Zusammenfassung:Due to steric repulsions, the cyclo­hexane ring in the title compound, C23H24N2O5·H2O, shows some bond‐length abnormalities and adopts a chair conformation. The pyrimidine and cyclo­hexane rings are approximately perpendicular to each other, and the phenyl rings are equatorial. C—H⋯π and N—H⋯O intermolecular interactions, as well as C—H⋯O inter‐ and intramolecular interactions, occur between the mol­ecules. In addition to van der Waals interactions, the water mol­ecule interacts with the pyrimidine­trione ring to stabilize the structure.
