Abstract

The reaction of the 17e nickel(I) radical [CpNi(IDipp)] (1, IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with P₄ results in a nickel tetraphosphide [{CpNi(IDipp)}₂(μ-η¹:η¹-P₄)] with a butterfly-P₄²⁻ ligand; related chalcogenides [{CpNi(IDipp)}₂(μ-E₂)] (E = S, Se, Te) and [{CpNi(IDipp)}₂(μ-E₃)] (E = S, Se) are formed with S₈, Se_∞ and Te_∞.
