Mol­ecules of the title compound, C14H10IN3O3, are linked into sheets by a combination of N—H⋯O and C—H⋯O hydrogen bonds.

Comment

The title compound, (I)[link], was prepared as part of our study of the supramolecular arrangements of imine and amido compounds.

[Scheme 1]

In the mol­ecules of (I)[link] (Fig. 1[link]), the bond distances (Table 1[link]) in the acyclic acyl­hydrazone fragment C11–C21 are all standard (Allen et al., 1987[Allen, F. H., Kennard, O., Watson, D. G., Brammer, L., Orpen, A. G. & Taylor, R. (1987). J. Chem. Soc. Perkin Trans. 2, pp. S1-19.]), and there is no evidence for any bond fixation within the ar­yl rings. Hence, the conventional representation (I)[link] is entirely appropriate. This central spacer unit is nearly planar, as shown by the key torsional angles, with a trans planar H—N—C=O fragment, as expected, and an E configuration at the C1=N1 bond. However, the ar­yl rings are both twisted out of this plane, making dihedral angles of 38.9 (2) and 43.3 (2)°, while the nitro group is twisted out of the plane of the adjacent ar­yl ring by 33.7 (2)°. Within the spacer unit C11–C21, the intra­chain bond angles are all less than 120°.

The mol­ecules of (I)[link] are linked into sheets by one N—H⋯O hydrogen bond and two C—H⋯O hydrogen bonds, one of which utilizes the carbon­yl O atom as acceptor, while the other utilizes a nitro O atom. Hydrazone atom N2 and methine atom C1 in the mol­ecule at (x, y, z) both act as hydrogen-bond donors to carbon­yl atom O2 in the mol­ecule at (x, −1 + y, z), thus generating by translation a C(4)C(6)[R21(6)] chain of rings (Bernstein et al., 1995[Bernstein, J., Davis, R. E., Shimoni, L. & Chang, N.-L. (1995). Angew. Chem. Int. Ed. Engl. 34, 1555-1573.]) running parallel to the [010] direction (Fig. 2[link]). It may be noted here that analogous C(4) motifs are rather common in both carboxamides and sulfonamides.

In addition, ar­yl atom C26 in the mol­ecule at (x, y, z) acts as hydrogen-bond donor to nitro atom O22 in the mol­ecule at (1 − x, −y, −[{1\over 2}] + z), thereby forming a C(11) chain, generated by the 21 screw axis along ([{1\over 2}], 0, z) and running parallel to the [001] direction (Fig. 3[link]). The combination of the simple [001] chains and the [010] chains of rings then generates a complex (100) sheet (Fig. 4[link]). This sheet lies in the domain 0.21 < x < 0.79 and a second such sheet, related to the first by the action of the glide planes, lies in the domain 0.71 < x < 1.29. However, there are no direction-specific inter­actions between adjacent sheets: in particular, C—H⋯π(arene) hydrogen bonds, aromatic ππ stacking inter­actions, and iodo–nitro inter­actions are all absent.

Experimental

The title compound was prepared by reaction of 2-nitro­benzaldehyde hydrazone with 2-iodo­benzo­yl chloride. A solution containg 2 mmol of each reactant in 1,2-dichloro­ethane (20 ml) was heated under reflux for 1 h; the mixture was cooled and the solvent was removed under reduced pressure. The solid residue was crystallized initially from ethanol, and crystals suitable for single-crystal X-ray diffraction were obtained by slow evaporation of a solution in ethanol and 2-propanol [1/1 (v/v), m.p. > 520 K]. IR (KBr disk): 1680 cm−1.
