Hydrogen-bonded nickel(i) complexes†
Abstract
A series of nickel(II) tris(2-pyridylmethyl)amine (TPA) complexes featuring appended hydrogen bonds (H-bonds) to halides (F, Cl, Br) was synthesized and charcterized. Reduction to the nickel(I) state provided access to an unusual nickel(I) fluoride complex stabilized by H-bonds, enabling structural and spectroscopic characterization.
