AbstractThe syntheses and characterization of alkalimetal complexes [{VO2L}M(H2O}n] (1 and 2) [M = Na+ (1), K+ (2)] of anionic cis-dioxovanadium(V) species (LVO2−) of the Schiff base 2-hydroxybenzoylhydrazone of 2-hydroxybenzaldehyde have been reported. The number of coordinated water molecules in [{VO2L}M(H2O}n] decreases as the charge density of the alkalimetal ion decreases (n = 5 for Na+ and 1 for K+). These compounds represented M+-mediatedsupramolecularassembly [{VO2L}M(H2O}n]∝ with an infinite polymeric structure containing an alternating array of cis-dioxo vanadium(V), [VO2L]−, units and aquated metal ion centres, as confirmed by X-ray crystallographic investigation of both. All the compounds are characterized by elemental analysis, IR, UV–Vis and NMR spectroscopy.
