1-Adamantylmethyl 2-aminobenzoate

Abstract

The asymmetric unit of the title compound, C18H23NO2, consists of two crystallographically independent molecules bearing an adamantane cage consisting of three fused cyclohexane rings in almost ideal chair conformations, with C—C—C angles in the range 108.47 (16)–110.59 (15)°. Both aryl rings are essentially planar, the maximum deviation from the best plane being 0.0125 (19) Å. One conformer forms chains parallel to the b axis via N—H...O hydrogen bonds, whereas the second exhibits only an intramolecular N—H...O hydrogen bond. The crystal structure is stabilized by further weak N—H...O and N—H...N interactions.
