Abstract
The synthesis, crystal structure, Hirshfeld analysis, and anti-fungal assessment of a new monohydrated Schiff base with a triazole moiety are reported. The structural study revealed the presence of three significant hydrogen bonds (N-H⋯N, O-H⋯N, and O-H⋯O), which contribute to the cohesion of the crystal. These bonds generate two-dimensional layers parallel to the bc plane, built on the basis of rings with the graph-set motifs R (4) (4)(8) and R (4) (4)(24). The crystal structure is further consolidated by π-π inter-actions between similar rings. The anti-fungal activity of the Schiff base was evaluated against three fungi: Fusarium oxysporum, Botrytis cinerea, and Alternaria alternata, showing significant anti-fungal activity, particularly against Alternaria alternata.
