The two aromatic rings of each of the four independent molecules in the 11H9ClN2, are approximately coplanar; the four molecules are arranged into two amino–pyridyl N—H⋯N hydrogen-bonded pairs. The structure has a 15% twin component related by a twofold rotation about [100].

2-Chloropyridine (0.5 ml, 5.28 mmol) and 4-chloroaniline (0.67 g, 5.28 mmol) were heated for 5 h. The mixture was cooled and extracted with ether (3 x 100 ml). The ether extract was washed with water and then dried over sodium sulfate. Evaporation of the solvent gave a purple colored powder. Recrystallization from chloroform yielded colorless prisms.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 Å) and were included in the
using the riding model approximation, with U(H) fixed at 1.2U(C). The amino H-atoms were similarly treated as riding (N–H 0.88 Å).The structure initially refined to a rather high R index of 8.26%, and the difference Fourier map showed relatively large peaks for an all-light atom structure, although none were larger than 1 e Å-3. A preliminary check with the TwinRotMat routine of PLATON (Spek, 2003) showed strong evidence twofold
about [1 0 0]. against the TwinRotMat-generated data gave a lower R index of 7.26% along with a considerably flatter final difference Fourier map (no peak larger than ca 0.5 e Å-3). According to TwinRotMat, should cause split reflections on the (n,k,l) layers with n = +/-1,2,3,4 although on some of these (e.g., n =+/- 1,4) the spot splitting was marginal. With n = -5,0,5 and on all (h,n,l) and (h,k,n) layers, the overlap was essentially perfect.On the other hand, the
diffraction data, when examined with the proprietary RLATT (Bruker, 2007) did not show any evidence of split reflections, most likely because the twin component is small.Data collection: APEX2 (Bruker, 2007); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

The class of compounds represented by the title compound (Scheme I, Fig. 1) exhibit fluorescence (Abdullah, 2005; Kawai et al., 2001; Mohd Salleh et al., 2007). The compound crystallizes with four indepedent molecules; in each molecule, the two aromatic rings are approximately coplanar. The four molecules are arranged into two H–Hamino–Npyridyl hydrogen-bonded pairs.
