P 4 activation but without reduction is the most striking result of the reaction of Ni I precursors (LNi) with white phosphorus. This reaction leads to the complexes 1 a and 1 b , which feature the scarce η 3 ‐coordination of the P 4 ligand between two metal centers. Remarkably, 1 a undergoes facile dissociation in solution to give the paramagnetic Ni I complex 2 . L=β‐diketiminate; 1 a : R= i Pr 2 C 6 H 3 , 1 b : R=2,6‐Et 2 C 6 H 3 .
