Özet
A new type of inclusion complex, S(-)-1 phenyl ethyl ammonium percholorate complex of R-(-)-2-ethyl-N-benzyl-4,7,10,13-tetraoxa-1-azacyclopentadecane, has been prepared and studied by NMR, IR and single crystal X-ray diffraction techniques. 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.
