Structural characterization and electrochemical properties of nickel (II) complexes bearing sterically bulky hydrotris(3-phenyl)- and hydrotris(3-tert-butylpyrazol-1-yl)borato ligands

A series of nickel (II) complexes bearing sterically bulky TpR (R = tert-butyl or phenyl) ligands were synthesized and structurally characterized. The redox properties of the nickel center were investigated and results indicate that the redox trends fall more in line with the electronic properties of the complexes than the structural differences.91
