title: rac-(rel-1R,2R,4S)-Spiro-[bicyclo-[2.2.1]heptane-2,3'-indol]-2'-amine.
abstract: In the racemic title compound, C(14)H(16)N(2), the aromatic ring component of the amino-indoline system occupies the endo cavity of the norbornane component. The aromatic ring lies at an angle of 74.12 (5)° to the plane defined by the four C atoms that comprises the rigid part of the boat-shaped six-membered ring of the norbornane unit. Pairs of mol-ecules assemble in the crystal structure, forming centrosymmetric hydrogen-bonded dimers via pairs of N-H⋯N hydrogen bonds through the syn H atom of the amine group.
