E. Weber et al., NEW MACROCYCLIC HOSTS FOR THE INCLUSION O F ORGANIC GUEST MOLECULES -CRYSTAL-STRUCTURE OF A COMPLEX WITH DIMETHYLFORMAMIDE (1 1)/, Journal fur praktische Chemie, Chemiker-Zeitung, 335(3), 1993, pp. 235-243
New pyridino crowns with amide and sulfonamide groups 1 b and 1 c are
synthesized. They form numerous stoichiometric crystalline inclusion c
omplexes with alcohols, various dipolar-aprotic solvents, as well as c
yclic ethers. Host-guest stoichiometries are discussed and inclusion s
electivities (relating to DMF) are shown. The structure of the crystal
line DMF inclusion compound of the sulfonamide host 1 c (1 : 1) is det
ermined by X-ray diffraction, showing a lattice void inclusion mode.
