[Display omitted] •Recent advances in 1,2,3-triazole-ligated complexes and their coordination behaviour are discussed.•Their utility as catalyst precursors in various transformations are discussed and classified according to the central metal atom.•The influence of coordination environment on catalytic performance is analysed.•Structure-activity relationships are discussed in the context of rational catalyst design. The study of transition metal complexes linked with 1,2,3-triazoles has gained significant attention due to their potential as effective catalysts in various chemical reactions. The 1,2,3-triazole moiety has been proven to be an excellent ligand in metal complex catalysis, primarily because of its unique electronic and steric properties. The ability to tune these properties through modifications to the triazole ligand allows for precise control over the reactivity and selectivity of the metal complex. This review provides a critical assessment of the recent advances made in the development of 1,2,3-triazolyl ligated transition metal complexes and their uses in catalysis with emphasis on how structural variation impacts on the catalytic performances of these complexes.
