Bis[N-cyclohexyl-1-(2-{1-[(cyclohexyl-amino)carbonyl]cyclohexyl}-3,5-dioxo-1,2-oxazolidin-4-yl)cyclopentanecarbox-amide] monohydrate.

The reaction of cyclo-hexyl isocyanide and alkyl-idene Meldrum's acid (systematic name 2,2-dimethyl-1,3-dioxane-4,6-dione) in the presence of cyclo-hexyl ketoxime and dichloro-methane as solvent resulted in the title compound, 2C(28)H(43)N(3)O(5)·H(2)O. One methyl-ene group of the cyclo-pentane ring was found to be disordered and was refined with occupancies 0.75:0.25. Intra-molecular N-H⋯O hydrogen bonds occur. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
