C17O6H26,monoclinic, space group P21, a = 8.710(2), b = 17.770(3), c = 11.250(2) A, β= 99.16(2)°, V = 1719.0A3, Z = 4, Dc = 1.26 g/cm3, μ(MoKα) = 1.0 cm-1, F(000) = 704. Crystal structure was solved by SHELXTL direct method and refined by least squares technique for 1623 independent reflections of I≥2.5(?)(Ⅰ) from Nicolet P3/R3 diffractometer. The results show that the crystal consists of two nonequivalent crown ether rings A and B, in which the related distances between O atoms are 2.68-6.14 A for A and 2.52-6.06 A for B respectively.
