Synthesis and crystal structure of a novel hexahomotrioxacalix[3]cryptand

A novel hexahomotrioxaacalix[3]cryptand was synthesized and its crystal structure has been determined. The crystals obtained by recrystallization from ethanol, are singal clinic, space group is C2/c, a = 19.6831(16)angstrom, b = 16.8180(16)angstrom. c = 29.267(3)angstrom, alpha = 90.00 degrees, beta = 105.222(4)degrees, gamma = 90.00 degrees. H-1 NMR spectroscopy and X-ray single-crystal structure results suggested that this compound was fixed in a cone conformation.
