Abstract Starting from easily accessible 3‐[2‐(diphenylphosphanyl)phenyl]‐1 H ‐pyrazole a series of four‐ and five‐coordinate diamagnetic nickel(II) complexes were synthesized and structurally characterized. The resulting complexes show dynamic NMR spectra reflecting a high degree of flexibility in the ligand backbone. Protonation and deprotonation of the pyrazole moiety allows interconversion of the nickel(II) complexes.
