Double-armed crown ether 15,16-bis((4-nitrophenoxy)methyl)-2,3,5,6,8,9,11,12-octahydrobenzo[b][1,4,7,10,13] pentaoxacyclopentadecine F.W. 570.54 was synthesized by dibromomethyl benzo-15-crown-5 with 4-nitrophenol in the presence of anhydrous K2CO3, characterized by spectroscopic techniques and confirmed by X-ray crystal structure analysis. The title compound crystallizes in monoclinic, space group P21/c with a = 12.840(4), b = 9.425(3), c = 22.447(7), β = 98.128(7)° and Z = 4. The structure exhibits intermolecular hydrogen bonding of C-H···O type.
