Abstract
In the solid-state structure of K(dioxane)2PPh2 (1), prepared from potassium and PPh3 in dioxane, each K ion is surrounded by four bridging dioxane molecules in a plane, and the P atom of the PPh2 anion occupies an axial position. A π interaction between the K ion and an aryl ring of a PPh2 anion of a neighbouring plane generates a three-dimensional network. 1 crystallises in the monoclinic space group P21/n (no. 14), T = 200(2) K, with a = 8.854(1) Å, b = 15.904(2) Å, c = 15.740(2) Å, β = 99.16(1)°, V = 2188.1(5) Å3 and Z = 4. The refinement converged to R1 = 0.0372, wR2 = 0.0949 (for reflections with I > 2σ(I)), R1 = 0.0871, wR2 = 0.1125 (all data).
