چکیده
The alkynyl bond of the title compound, C(14)H(19)NO, has a length of 1.170 (5) Å. The amide function shows a trans conformation with respect to the carbonyl group characterized by the torsion angle O-C-N-H of -176 (2)°. There is an inter-molecular N-H⋯O hydrogen bond between the amide function and the carbonyl group. In addition, weak inter-molecular hydrogen bonds stabilize the crystal structure. A comparison with a polymorphic structure shows conformational differences with regard to the orientation of the carbonyl groups with respect to the adamantyl group [O-C-C-C = 96.2 (3)° in the title compound and 123.7 (2)° in the polymorph] and the orientations of the propargyl groups in relation to the carbonyl groups [O-C-C-C = -87.7 (3) and -58.7 (2)°, respectively].

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.
