| 摘 要： | The title complex K(2,2,2-crypt)]3Sb11 has been prepared by the reaction of K3Cd2Sb with Cu-C≡CH in ethylenediamine in the presence of 2,2,2-crypt, and characterized by low temperature X-ray structure analysis. The crystal is of orthorhombic system, space group C2221 with a = 15.475(3), b = 22.807(5), c = 24.834(6), V = 8765(3)3, Dc = 1.960 g/cm3, C54H108K3N6O18Sb11, Mr = 2586.01, F(000) = 4944, μ = 3.531 mm-1, Z = 4, R = 0.0442 and wR = 0.1053 for 10265 observed reflections (I > 2σ(I)). The "naked" Sb113- anion is stable due to the completely sequestered alkali metal cations through ion-ion interactions.
