The reactivity of white phosphorus and yellow arsenic towards two different nickel nacnac complexes is investigated. The nickel complexes [(L 1 Ni) 2 tol] ( 1 , L 1 =[{N(C 6 H 3 i Pr 2 ‐2,6)C(Me)} 2 CH] − ) and [K 2 ][(L 1 Ni) 2 (μ,η 1 : 1 ‐N 2 )] ( 6 ) were reacted with P 4 , As 4 and the interpnictogen compound AsP 3 , respectively, yielding the homobimetallic complexes [(L 1 Ni) 2 (μ‐η 2 ,κ 1 :η 2 ,κ 1 ‐E 4 )] (E=P ( 2 a ), As ( 2 b ), AsP 3 ( 2 c )), [(L 1 Ni) 2 (μ,η 3 : 3 ‐E 3 )] (E=P ( 3 a ), As ( 3 b )) and [K@18‐c‐6(thf) 2 ][L 1 Ni(η 1 : 1 ‐E 4 )] (E=P ( 7 a ), As ( 7 b )), respectively. Heating of 2 a , 2 b or 2 c also leads to the formation of 3 a or 3 b . Furthermore, the reactivity of these compounds towards reduction agents was investigated, leading to [K 2 ][(L 1 Ni) 2 (μ,η 2 : 2 ‐P 4 )] ( 4 ) and [K@18‐c‐6(thf) 3 ][(L 1 Ni) 2 (μ,η 3 : 3 ‐E 3 )] (E=P ( 5 a ), As ( 5 b )), respectively. Compound 4 shows an unusual planarization of the initial Ni 2 P 4 ‐prism. All products were comprehensively characterized by crystallographic and spectroscopic methods.
