Abstract
In the title compound, C9H15NO·C6H2Cl2O4 [sytematic name: 2-azaspiro[4.5]decan-3-one–chloranilic acid (1/1)], the cyclohexane ring of the lactam molecule adopts a slightly distorted normal chair conformation and the five-membered 3-azaspiro ring is in a slightly distorted chair conformation. The dihedral angle between the least-squares planes of the cyclohexane and 3-azaspiro rings is 84.0 (3)°. In the crystal, the chloranilic acid molecule and the gabapentin-lactum molecules are held together by strong intermolecular N—H⋯O and O—H⋯O hydrogen bonds with two bifurcated O acceptor atoms on the chloranilic acid molecule and one on the gabapentin-lactum molecule, each bonding with an inter- and intramolecular hydrogen bond. The molecules are linked into chains parallel to (011) and propagating along the b axis.
