Abstract

The cationic complexes, [TpRNi(bpym)]+ {TpR = tris(3,5-diphenylpyrazolyl)borate, R = Ph2 1; tris(3-phenyl-5-methylpyrazolyl)borate, R = Ph,Me 2} were synthesized by reacting [TpRNiBr] (R = Ph2; Ph,Me) with bipyrimidine followed by subsequent addition of KPF6 in CH2Cl2. The green solids have been characterized by IR, UV–Vis and 1H NMR spectroscopy. Crystallographic studies of [TpPh,MeNi(bpym)]PF6 reveal a five-coordinate square pyramidal nickel centre with a κ3-coordinated TpPh,Me ligand and a chelating bipyrimidine ligand. Cyclic voltammetric studies show irreversible reduction with the degree of reversibility dependent on the type of TpR ligand.
