Insecticides. Part IV. Crystal structure of Heptachlor (racemic 1,4,5,6,7,8,8-Heptachloro-3a,4,7,7a-tetrahydro-4,7-methanoindene)

Abstract

The crystal structure of Heptachlor was determined by the symbolic addition procedure from three-dimensional diffractometer data with 1239 reflections. Z= 8 in the orthorhombic unit cell, space group, Pbca, a= 1580·0(1), b= 1421·5(1), and c= 1266·6(1) pm. The structure was refined by least squares to R 0·047. The major difference between Aldrin, Endrin, and Heptachlor is that the nonchlorinated methanocyclohexane ring in the first two is replaced by a chlorocyclopentene system.
