The title compound has been investigated by x-ray analysis and AMI semi-empirical quantum mechanical method. The geometry of the two molecules in the asymmetric unit is different in tenus of the torsion angle θ [ C4-C5-C6-C10 ] between the two pryidine rings which is -34.1 (2)° and -17.9 (2)° in molecule I and II respectively. The conformation of the energy profile showed that the minimum energy conformation has the torsion angle θ near 35°. The crystal structure is stabilized by C-H ... N hydrogen bonds.
