title: (3aRS,4SR,7RS,7aSR)-2-(Tricyclo-[3.3.1.1]decan-1-yl)-4,5,6,7-tetra-hydro-4,7-epoxy-isoindoline-1,3-dione.
abstract: The title compound, C(18)H(23)NO(3), the adamantane derivative of norcantharidin, which is itself derived from cantharidin, crystallized with three independent mol-ecules in the asymmetric unit. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O inter-actions, leading to the formation of a supra-molecular two-dimensional network.
