This review focuses on the interaction between the essential element‑vanadium with 1,10-phenanthroline and polypyridyl ligands. It starts with a summary of the prior work on speciation studies for the binary systems vanadium-phenanthroline alongside several hydrolytic studies of the metal ion. It also includes a complete overview on the different X-ray structures known to date with discussions on the potential cytotoxic activity of several vanadium-polypyridyl complexes.
Keywords: Anticancer activity; Cytotoxicity; Polypyridyl ligands; Speciation studies; Vanadium; Vanadium-based complexes.
