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.
标题化合物 C13H8I2N2O3 的分子通过一个 N-H...O=C 氢键 [H...O = 2.10 Å,N...O = 2.832 (5) Å,N-H...O = 140°]连接成 C(4) 链。两个独立的双中心碘-硝基相互作用涉及相同的 O 原子和不同的 I 原子[I...O = 3.205 (3) Å 和 3.400 (3) Å,C-I...O = 160.4 (2) Å 和 155.7 (2) Å],将氢键链连接成双层膜。
