4,7-Diiodo-2,1,3-benzothiadiazole and 7,7'-diiodo-4,4'-bi(2,1,3-benzothiadiazole).
In the crystal structures of the title compounds, C(6)H(2)I(2)N(2)S, (I), and C(12)H(4)I(2)N(4)S(2), (II), respectively, a large number of short inter-heteroatom contacts, such as S...N, I...I and N...I, are observed. In (II), which is non-centrosymmetric, two halves of the molecule are related by a crystallographic twofold axis.
