Synthesis, crystal structure and Hirshfeld surface analysis of 5-[2-(di­cyano­methyl­idene)hydrazin-1-yl]-2,4,6-tri­iodo­isophthalic acid ethanol monosolvate

The title compound, C(11)H(3)I(3)N(4)O(4)·C(2)H(6)O, crystallizes in the triclinic P [Image: see text] space group with one independent mol­ecule and one ethanol solvent mol­ecule in the asymmetric unit. The benzene ring and the methyl­carbonohydrazonoyl dicyanide group of the main mol­ecule makes a dihedral angle of 57.91 (16)°. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link pairs of mol­ecules, forming dimers with R (2) (2)(14) motifs. These dimers are connected by O—H⋯O hydrogen bonds into chains along the a-axis direction, forming R (2) (2)(16) ring motifs. Further O—H⋯O inter­actions involving the ethanol solvent mol­ecule connect the chains into a three-dimensional network. In addition, C—I⋯π inter­actions are observed. The inter­molecular inter­actions in the crystal structure were qu­anti­fied and analysed using Hirshfeld surface analysis.
