The reaction of the 17 e nickel( i ) radical [CpNi(IDipp)] (1, IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with P 4 results in a nickel tetraphosphide [{CpNi(IDipp)} 2 (μ-η 1 :η 1 -P 4 )] with a butterfly-P 4 2− ligand; related chalcogenides [{CpNi(IDipp)} 2 (μ-E 2 )] (E = S, Se, Te) and [{CpNi(IDipp)} 2 (μ-E 3 )] (E = S, Se) are formed with S 8 , Se ∞ and Te ∞ .
