Abstract: | Molecules of the title compound, C13H8I2N2O3, are linked into C(4) chains by a single N—H?O=C hydrogen bond H?O = 2.10 Å, N?O = 2.832 (5) Å and N—H?O = 140°]. Two independent two‐centre iodo–nitro interactions, both involving the same O atom but different I atoms I?O = 3.205 (3) and 3.400 (3) Å, and C—I?O = 160.4 (2) and 155.7 (2)°], link the hydrogen‐bonded chains into bilayers. |
