inecarboxamide provides [N-(2,6-diisopropyl)phenyl-2-pyridinecarboxamidatotris(pentafluorophenyl)borate-κ2N,N]Ni(η3-CH2CMeCH2) (4) in 92% yield. The solid-state structures of 3 and 4 were determined by X-ray diffraction techniques. The intramolecular metrical parameters are consistent with substantial partial positive charge at the nickel atom. Deprotonation of N-(2,6-diisopropyl)phenyl-2-pyridinecarboxamide
