NiCl 2 · 6 H 2 O readily reacts with PPh 2 NHPh in the presence of zinc dust to yield the homoleptic nickel(0) tetrakis‐phosphine complex [Ni(PPh 2 NHPh) 4 ] ( 1 ). 1 crystallises triclinic P 1 (no. 2), with a = 14.656(1), b = 17.124(2), c = 17.424(1) Å, α = 95.998(1), β = 111.845(1), γ = 111.402(1)°, V = 3630.04(5) Å 3 , Z = 2, R values [ I > 2σ( I )]: R 1 = 0.0554, all data: wR 2 = 0.1720. The nickel atom is coordinated in a distorted tetrahedral fashion by four phosphorus atoms, resembling a compressed tetrahedron along one of the non‐crystallographic S 4 axes.
