The title compound, [Ni(C18H30FO2P2)(C3H4N2)]PF6, was prepared by halide abstraction with TlPF6 in the presence of CH3CN in CDCl3 from the respective neutral pincer chlorido analogue followed by addition of pyrazole. The PO—C—OP pincer ligand act

Hexakis(meta-fluoro)substituted triphenylmethyl cation (F6Tr+) was isolated with a carborane partner anion. Its significantly higher hydride affinity compared to the parent (Tr+) allows it to abstract hydrides from a variety of C(sp3)–H bonds.
