title: Crystal structure of cis-1-(2-methyl-1,2,3,4-tetra-hydro-quinolin-4-yl)azepan-2-one.
abstract: In the title compound, C16H22N2O, the azepan-2-one ring adopts a chair conformation, while the 1,2,3,4-tetra-hydro-pyridine ring adopts a half-chair conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming supra-molecular chains propagated along [10-1], with weak C-H⋯O inter-actions occurring between the chains.
