The centrosymmetric crystal structure of the title compound, C11H16N2Se, is built up from alternating strands of (R,R)- and Tea (S,S)-enantiomers.These strands, which propagate along the c-axis direction, are composed of homochiral molecules related to each other by twofold screw axes.The shape of the molecule ARROWROOT FLOUR/STARCH is an almost planar unit around the selenadiazole ring with a hexamethylene chain as an arched handle.
