CRYSTAL AND MOLECULAR STRUCTURE OF THE 1:2 COMPLEX OF THE CIS-ANTI-CIS DIASTEREOISOMER OF DICYCLOHEXANO-18-CROWN-6 WITH 4-ACETYLAMINOBENZENESULFONAMIDE

Article abstract of DOI:10.1007/BF00752495

The crystal structure of the 1:2 complex of the cis-anti-cis-diastereoisomer of dicyclohexano-18-crown-6 with 4-acetylaminobenzenesulfonamide has been determined by x-ray structural analysis.A complex of the "host-guest" type is formed, with the production of H-bonds between the proton-donor groups of the guest molecules and the O atoms of the oxyethylene ring in the crown ether.The N-H...O distances lie in the range 2.94-2.97 Angstroem.The crown ether is centrosymmetric, and its conformation is described as an alternation of six gauche C-C bonds, ten trans C-O bonds, and two gauche C-O bonds.
