Unexpectedly, the complexes 3a and 3b feature a [Si(μ,η2:2-P4)Ni] core with nickel(I) centers as shown by X-ray diffraction analysis, electron paramagnetic resonance, and magnetic measurements. The latter prove that the products are paramagnetic both in the solid state and in solution because of the presence of tetrahedral nickel(I) sites.
