N,N'-Dimethyl-1,4-dithiine-1,2:4,5-tetracarboximide and N,N'-dimethyl-1,4-diselenine-1,2:4,5-tetracarboximide

N,N'-Dimethyl-1,4-dithiine-1,2:4,5-tetracarboximide and... The title compounds of sulfur, C10H6N2O4S2, (I), and selenium, C10H6N2O4Se2, (II), are isomorphous. The crystallographically centrosymmetric molecules are planar. The bond distances and angles, except for those involving the S and Se atoms, are comparable. The molecules are disposed in layers parallel to the bc plane. The molecular axes differ by 75Degrees for (I) and by 80Degrees for (II) from one layer to the next. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section C: Crystal Structure Communications International Union of Crystallography
