THE CRYSTAL STRUCTURE OF 1,3-DICHLORONAPHTHALENE

Abstract

Crystals of 1,3-dichloronaphthalene are monoclinic with four molecules in a unit cell of dimensions a = 15.11, b = 3.92, c = 14.86 Å; β = 96.0°; space group P21/n. The x and z parameters of the chlorine and carbon atoms have been determined from Patterson and Fourier projections along the b-axis. The bond distances in the molecule, determined from the lengths projected on (010) together with estimated orientation angles, are very similar to the corresponding distances in naphthalene.
