Mr= 3584.7, monoclinic, P21/c, a = 14.647(2), b = 20.333(2), c = 25.759(3) A, β= 91.05(1)°, Z = 2, V = 7670.1 A3, Dc = 1.544 g/cm3,μ=32.629 cm-1, R=0.056 for 4207 observed reflections. Each asymmetric unit consists of two UO2Cl42- complex anions and three C20B36O6-H3O+ complex cations. In two of the complex cations (isosaer A), HaO+ cation is anchored in each crown ether ring by three stronger hydrogen bonds. In another complex cation (isomer B) only two stronger hydronger bonds are formed between the H3O+ cation and crown ether. The third hydrogen bond is very weak.
