3-Methyl-4,5,6,7,8,9-hexahydrocycloocteno-1,2,3-selenadiazolium iodide–trichloromethane (4/1)

Abstract

The title solvated salt, 4C9H15N2Se+·4I−·CHCl3, co-crystallizes with chloroform. The asymmetric unit contains four very similar ion pairs and one solvent molecule. In the crystal, layers of parallel chloroform-filled channels formed by two different ion pairs alternate with layers formed by the other two ion pairs. Disorder is observed for some C and H atoms in two of the cations with occupancy ratios of 0.68:0.32 and 0.62:0.38.
