Abstract

The crystal structure of endrin was determined by Patterson and Fourier methods from three-dimensional diffractometer data with 753 reflections. Z = 4 in the orthorhombic unit cell, space group, P2₁2₁2₁, a= 1530·4(2), b= 1148·6(1), and c= 820·2(1) pm. The structure was refined by least-squares to R 0·044. The crystal structure of aldrin, was determined by the symbolic addition procedure from three-dimensional diffractometer data with 1080 reflections. Z = 4 in the monoclinic unit cell, space group P2₁/n, a= 1080·6(1), b= 1474·3(2), c= 899·2(1) pm, β= 93·03(1)°, the structure was refined to R 0·048.
