Conformational studies. Part V. The crystal and molecular structures of dimethyl meso-ββ′-dichloroadipate
Abstract
The crystal and molecular structures of the title compound have been solved from three-dimensional photographic data by Patterson techniques and refined by least-squares methods to R 0·060 for 837 observed reflections. The centrosymmetric molecule results in a conformation in which the two chlorine atoms are maximally separated; the halogen is gauche along the Cα–Cβ bond in the methoxycarbonyl group. Crystals are monoclinic, a= 8·300(4), b= 5·626(2), c= 12·616(5)Å, β= 91·29(8)°, Z= 2, space group P2/n.
