The title compounds, 2,6-di-iodo-4-nitro-toluene (DINT, CHINO) and 2,4,6-tri-bromo-toluene (TBT, CHBr,), are tris-ubstituted toluene mol-ecules. Both mol-ecules are planar, only the H atoms of the methyl group, and the nitro group in DINT, deviate significantly from the plane of the benzene ring. In the crystals of both compounds, mol-ecules stack in columns up the shortest crystallographic axis, .

Article Synopsis
  • The compound C5H4Cl2N2 has a nearly flat structure, with non-hydrogen atoms deviating only slightly from a mean plane.
  • The maximum deviation from this plane is found in a nitrogen atom, measuring just 0.016 Å.
  • In the crystal structure, molecules are connected through C-H⋯N hydrogen bonds, creating inversion dimers that form a specific ring pattern (R (2) 2(6)).
