The perfluoro-1,2,4-triazoles are known to be effective ligands. For instance, a number of charge neutral Os(II) pyridyl-l,2,4-triazolate complexes with either bis(diphenylphosphino)methane 93 or ct>l,2-bis(diphenylphosphino)ethene 94 chelates were synthesized, and their structural, electrochemical, photophysical properties and thermodynamic relationships were established [89, 90], Chi, Carty et al. synthesized 6-(3-trifluoromethyl-l,2,4-triazolyl)-2,2 -bipyridine and built up on this basis tridentate 6-azolyl-2,2 -bipyridine chelate complex compounds of Ga and In 95 [91],... 

The acid-base properties of the ground and excited states of [Ru(bpy)2(im)2] and [Ru(bpy)2(l,2,4-triazole)2] have been investigated. Both complexes are stronger acids in the excited than the ground states." Representative triazoles, L or HL, have been incorporated into the complexes [Ru(bpy)2L]"" (n = 1 or 2). Electronic spectroscopic and electrochemical properties have been reported all the ligands are weaker tt acceptors than bpy." " The crystal structures of...
