摘要
The undecaphosphide anion in ethylenediamine/18-crown-6 solution is isolated as [K（18-crown-6）]3P11·2en 1. The crystal structure has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21 with α = 13.4731（7）, b = 16.1123（6）, c = 16.5117（9） A, β = 112.133（2）°, Y = 3320.3（3） A3, Dc = 1.371 g/cm^3, C40H88K3N4O18P11, Mr = 1371.11, F（000） = 1444,μ = 0.532 mm^-1, Z= 2, R = 0.0544 and wR = 0.1326 for 11423 observed reflections （I 〉 20（I））. The ＂naked＂ P11^3- ion is stabilized by two partly sequestered potassiums, The third partly sequestered potassium does not interact with the P atom （P（6）） but with two solvent molecules.
