Abstract

The new organometallic nickel complex [(Phbpy)NiBr] containing the anionic tridentate N,N,C ligand 6-(phen-2-yl)-2,2'-bipyridine (Phbpy) was synthesised from PhbpyBr and [Ni(COD)(2)] in excellent yields and was fully characterised (MS, NMR, single crystal XRD). [(Phbpy) NiBr] was reacted with (CF3)SiMe3 giving the CF3 complex [(Phbpy)Ni(CF3)]. Both new complexes were studied in detail by electrochemical (CV) and spectroelectrochemical (UV/vis/NIR absorption) methods. For both complexes the first one-electron reduction and the first oxidation of the Br complex occur fully reversible in the CV, while spectroelectrochemistry shows decomposition reactions. The CF3 complex is unstable in solution producing 2-CF3-Phbpy. Reactivity patterns for these reactions were discussed, also in comparison with the non-cyclometalated complex [(bpy)Ni(Mes)Br].
