文摘

Uncommon Ni^I cationic complexes were synthesized by treating [Ni(ECp*)₂(PPh₃)₂] (E = Al, Ga; Cp* = pentamethylcyclopentadienyl) with 1 equiv of [FeCp₂][BAr₄^F]. 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.
