3-Methyl-4,5,6,7,8,9-hexahydrocycloocta[d][1,2,3]selenadiazol]-3-ium iodide triiodide (3/2/1)

Abstract

The title compound, 3C9H15N2Se+·I3−·2I−, was prepared by methylation of the selenadiazole with methyl iodide. The asymmetric unit is composed of three independent selenadiazolium ions arranged in layers and connectedviaI3−·(I−)2anion layers. The distances between the iodine and selenium atoms are significantly shorter than the nitrogen-to-iodine distances.
