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 (C_s) symmetry, and as predicted from earlier chemical studies, the chlorine atoms are in the exo-positions on the norbornane ring.
