The title compound crystallizes in the triclinic space group P(1) with one independent molecule and one ethanol solvent molecule. The crystal exhibits hydrogen bonding and dimer motifs, as well as C-I···π interactions.
The title compound, C11H3I3N4O4 center dot C2H6O, crystallizes in the triclinic P (1) over bar 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)degrees. In the crystal, O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds link pairs of molecules, forming dimers with R-2(2) (14) motifs. These dimers are connected by O-H center dot center dot center dot O hydrogen bonds into chains along the a-axis direction, forming R22 (16) ring motifs. Further O-H center dot center dot center dot O interactions involving the ethanol solvent molecule connect the chains into a three-dimensional network. In addition, C-I center dot center dot center dot pi interactions are observed. The intermolecular interactions in the crystal structure were quantified and analysed using Hirshfeld surface analysis.
