Crystal and molecular structure of exo-2,exo-3-dichloro-endo-5,6-(o-phenylene)norbornane
Abstract
The crystal structure of the title compound (2) has been determined from X-ray diffraction data collected by diffractometer. Crystals are orthorhombic, space group Pnma, with Z= 4 in a unit cell of dimensions a= 7.503(3), b= 11.022(5), and c= 13.429(6)Å at 21 °C. The structure was refined by full-matrix least-squares to a final (conventional)R value of 0.083 for 928 observed reflections. The molecule has crystallographically required mirror (Cs) symmetry, and as predicted from earlier chemical studies, the chlorine atoms are in the exo-positions on the norbornane ring.
