Verdazyls in Coordination Chemistry

The present minireview describing the mono- and biradical structures of heterocyclic radicals (verdazyls) in the role of ligands and types of their metal complexes is based on an analysis of scientific literature published since 2000 to 2021. In the majority of cases, monoverdazyl radicals in the composition of the complexes are described as N,N-bidentate or N,N,N-tridentate redox-active ligands. The verdazyl-containing biradical systems are considered. Examples of other verdazyl compounds with metals are presented.
