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 a = 13.4731(7), b = 16.1123(6), c = 16.5117(9) , β = 112.133(2)°, V = 3320.3(3) 3, Dc = 1.371 g/cm3, 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 > 2σ(I)). The “naked” P113-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.
