Oxidation of Ni-ECp* Complexes: Stable Open-Shell Ni-I Cations [Ni(ECp*)(n)(PPh3)(4-n)](+) (n=2, 4; E = Al, Ga)
Uncommon cationic complexes were synthesized by treating [Ni(ECp*)(2)(PPh3)(2)] (E = Al, Ga; Cp* = pentamethylcydopentadienyl) with 1 equiv of [FeCp2][BAr4F]. All compounds have been prepared readily in high yield. The paramagnetic compounds were characterized by single-crystal X-ray crystallography, mass spectrometry elemental analysis, magnetic susceptibility, and electron paramagnetic resonance spectroscopy.
