Abstract
Mutual recognition of iodo and nitro groups through symmetrical iodo–nitro bridging interactions generates symmetrical molecular ribbons in the crystal structure of the 1 : 1 complex of 1,4-diiodobenzene 1 with 1,4-dinitrobenzene 2; however, in the crystal structure of the 1 : 1 complex of 1 with TCNQ, the mediation of simple, non-bridging –I NC interactions leads to the formation of skewed ribbons.Keywords
