Crystal and molecular structure of cis-5,6,6a,7,8,9,10,10a-octahydro-5-methyl-10a-p-tolylsulphonylamino-6-p-tolylsulphonyliminophenanthridine

Abstract

The structure of the title compound has been determined from X-ray data by direct methods. Crystals are monoclinic, a= 12.509 ± 0.007, b= 14.197 ± 0.004, c= 15.666 ± 0.009 Å, β= 102.10 ± 0.03°, space group P2₁/n. 3 099 Reflections were used and the structure refined by full-matrix least squares to R 0.043. The crystals are formed without intermolecular hydrogen bonding. Interatomic distances and interbond angles are unexceptional. The N–S bonds at the imino-(1.610 Å) and amino-(1.606 Å) nitrogen atoms are not significantly different. The molecular conformation is described.
