Cyclohexane-1-spiro-2′-imidazolidine-5′-spiro-1′′-cyclohexan-4′-one
In the title compound, C(13)H(22)N(2)O, the central imidazolidine ring is in an envelope conformation and the two cyclo-hexane rings adopt chair conformations. In the crystal structure, the mol-ecules are linked into centrosymmetric R(2) (2)(8) dimers by pairs of N-H⋯O hydrogen bonds.

The molecule of the title compound, C(13)H(10)N(2)O(4), is nearly planar with a dihedral angle between the two aromatic rings of 2.24 (9)°. The NH group forms an intramolecular hydrogen bond with the carbonyl O atom. The mol-ecules form dimers about inversion centers in the crystal structure via inter-molecular O-H⋯O hydrogen bonds.
