Six bis‐tridentate and two tris‐bidentate cyclometalated ruthenium complexes with a 1,2,3‐triazole‐containing ligand have been prepared and characterized. Single‐crystal X‐ray analyses of complexes [(MeOptpy)Ru(Budtab)](PF 6 ) and [(Mebip)Ru(Budtab)](PF 6 ) are presented, where MeOptpy is 4′‐ p ‐methoxyphenyl‐2,2′:6′,2′′‐terpyridine, Budtab is the 2‐deprotonated form of 1,3‐di( N ‐ n ‐butyl‐1,2,3‐triazol‐4‐yl)benzene, and Mebip is bis( N ‐methyl‐benzimidazolyl)pyridine. The electronic properties of these complexes are probed by spectroscopic and electrochemical analyses. Time‐dependent density functional theory calculations have been performed to assist the assignment of the absorption spectra.
