Abstract
The title compound, C15H19NO4, contains one crystallographically independent molecule in the asymmetric unit. The N—O—C—O torsion angle is 1.97 (9)°. The two pairs of vicinal H atoms that lie above or below the plane defined by the five-membered pyrrolidine-2,5-dione ring are an average of 6.57 (5)° from being eclipsed. The average absolute C—C—C—C torsion angle in the adamantane skeleton, in which each fused cyclohexane ring is in a chair configuration, is 59.99 (5)°. The crystal packing is unremarkable.
