The reaction of potassium vanadate and the hydrazone ligand derived from Schiff base condensation of salicylaldehyde and biphenyl‐4‐carboxylic acid hydrazide (H 2 salhybiph) in the presence of β‐cyclodextrin (β‐CD) in water yields the 1:1 inclusion compound K[VO 2 (salhybiph)@ β‐CD]. The characterization in solution confirmed the integrity of the inclusion compound in different polar solvents such as DMSO and water. The inclusion compound crystallizes with additional water molecules in the triclinic space group P 1. The supramolecular aggregation of the inclusion compound in the solid state is established through hydrogen bonding interactions between adjacent β‐CD hosts and the π–π stacking ability of the ligand side chain of the guest complexes.
