Abstract: The supramolecular structures of the three isomeric (E,E)-1-(2-iodophenyl)-4-(2/3/4-nitrophenyl)-2,3-diaza-1,3-butadienes, C14H10IN3O2, are compared. In the 2-nitro isomer, the molecules are disordered across centres of inversion in space group C2/c and are linked into chains by a two-centre iodo-nitro interaction. The molecules of the 3-nitro isomer are linked into a three-dimensional framework by a combination of C-H
O and C-HI hydrogen bonds and aromatic ![[bold pi]](/logos/entities/pi_bdgif.gif)
- stacking interactions, while molecules of the 4-nitro isomer are linked into sheets by a C-HO hydrogen bond and a two-centre iodo-nitro interaction.
Formula: Three isomers of C14H10IN3O2

If the supplementary material that you require is not shown in the list above, it may only be available in our hard-copy archive. However, our policy is to progressively digitize old hard-copy supplementary documents where possible.
Please help us to work towards this goal by completing the form below. This will register your wish to receive a supplementary document, which we shall scan to create a PDF and then make available via the web to you and to other requestors in the future.
