The crystal structure of 2-Chloroquinoline was refined by least squares method, using three-dimensional intensity data collected at -140° C. The crystals are orthorombic, space group P 21 21 21 with four molecules in a unit cell of dimensions (at -140° C): a = 10,24 Å, b = 18,31 Å, c = 3,89 Å. The molecules are nearly planar and are stacked in columns with an intermolecular spacing of 3.43 Å.
