NaPPh 2 , prepared from sodium and PClPh 2 in refluxing dioxane, crystallises from dioxane as [Na 4 (μ‐dioxane) 8/2 (μ‐dioxane)(PPh 2 ) 4 ] ∞ ( 1 ), in which the basic structural features are eight‐membered Na 4 P 4 rings, linked by intermolecularly bridging dioxane molecules to give a three‐dimensional network, and inclusion of one dioxane molecule inside the eight‐membered ring. 1 crystallises in the orthorhombic space group Cmc2 1 (no. 36), T = 203(2) K, a = 27.377(1) Å, b = 10.579(1) Å, c = 23.608(1) Å, V = 6837.3(6) Å 3 , Z = 4, and the absolute structure parameter 0.3(2). The refinement converged to R1 = 0.0632, wR2 = 0.1701 (for reflections with I > 2σ(I)), R1 = 0.0707, wR2 = 0.1781 (all data).
