title: 3-(1-Adamantylamino)-3-methyl-1-phenyl-quinoline-2,4(1H,3H)-dione.
abstract: The structure of the title compound, C(26)H(28)N(2)O(2), contains essentially planar quinoline and benzene rings, the maximum deviations from the best plane being 0.086 (2) and 0.0056 (19) Å, respectively; the dihedral angle between the rings is 82.87 (4)°. The adamantane cage consists of three fused cyclo-hexane rings in classical chair conformations, with C-C-C angles in the range 107.85 (15)-111.35 (15)°. Enanti-omers are linked alternately into chains along the c axis via short N-H⋯O inter-actions and further C-H⋯π inter-actions stabilize pairs of enanti-omers, forming a two-dimensional network.
