The compound crystallizes in space group P2(1) with cell dimensions a = 10.0000(8), b - 12.281(2), c = 12.331(1)Angstrom, beta = 102.052(7), Z = 2. The host-guest complex is held together by a strong system of hydrogen bonds between the two protons of the ammonium ion as well as the nitrogen and four oxygen atoms of the crown ether The C-O and C-C distances of the 15-membered ring average 1.418 and 1.501 Angstrom while the O-C-C and C-O-C angles average 110.2 and 113.3degrees. The average N-C distance is 1.476 Angstrom.eninfo:eu-repo/semantics/closedAccess[No Keyword]Crystal structure of an inclusion complex between chiral monoaza-15-crown-5 and S(-)-1-phenyl-ethyl ammonium percholorateCrystal structure of an inclusion complex between chiral monoaza-15-crown-5 and S(-)-1-phenyl-ethyl ammonium percholorateArticle2185381384WOS:0001833321000082-s2.0-004230504110.1524/zkri.218.5.381.20734N/AQ2
