Pyridyltriazole ligands

CO)3Cl] (32a-l) by refluxing a stoichiometric mixture of the corresponding pyridyltriazole ligand and [Re(CO)5Cl] in an alcoholic solvent. Spectroscopic methods indicate that the expected/ac isomers are generated exclusively, and this has been confirmed by X-ray crystallography (Fig. 8c). The electronic spectra of... 

We now consider mononuclear complexes of the type [Ru(phen)2L] + (L phen). Complexes of general formula [Ru(phen)2(pyridyltriazole)] + have been prepared and characterized comparisons with related series of complexes containing 4,4 -Mc2bpy or bpy in place of phen have shown differences in the isomers formed. " The effects on the structure of [Ru(phen)3] + of exchanging one phen ligand for the sterically hindered 2,9-Me2phen have been investigated. Sterically... 

Rowan and coworkers have reported a series of Ir(III)-containing complexes constructed from ligands containing pyridyltriazole coordinating tmits [226]. Parallel and antiparallel ligands with cyclometallated [Ir(ppy)2] tmits binding to each of one, two, or three pyridyltriazole units were prepared, and studies of their photophysical properties showed that each Ir center behaves independent of the others. No structural characterization of the complexes was reported.
