X‐ray powder data have been obtained for the three title compounds, fundamental members of a group of psychotropic drugs. For the first two compounds, the crystal structures of which have previously been solved [Reboul, Cristau, Soyfer & Estienne (1980). Acta Cryst. B 36 , 2683–2688; Reboul, Cristau, Estienne & Astier, (1980). Acta Cryst. B 36 , 2108–2112], the powder patterns were indexed on the basis of an orthorhombic unit cell with the lattice constants a = 8.22 (1), b = 20.40 (1), c = 6.03 (1) Å, space group Pnma for C 14 H 11 N; C 14 H 13 N is monoclinic, space group P 2 1 / c with a = 11.60 (1), b = 11.27 (1), c = 20.05 (1) Å, and β = 126.5 (1)°. C 14 H 12 ClN is also monoclinic, P 2 1 or P 2 1 / m , with Z = 2, a = 11.68 (1), b = 8.08 (1), c = 12.13 (1) Å and β = 95.6 (1)°. The JCPDS Diffraction File Nos. for these compounds are: C 14 H 11 N 34‐1995; C 14 H 13 N 34‐1996, C 14 H 12 ClN 34‐1994.
