THE CRYSTAL-STRUCTURE OF )-(6-AMINOHEXYL)AMINO-6(I)-DEOXYCYCLOMALTOHEPTAOSE

The monosubstituted cyclomaltoheptaose derivative, -(6-aminohexyl)amin o-6(1)-deoxycyclomaltoheptaose, crystallizes in the orthorhombic space group P2(1)2(1)2(1) with a = 32.513(2), b = 15.3871(9), c = 15.2645(9 ) Angstrom, V = 7636.6(8) Angstrom(3) and Z = 4. The macrocycles are s pirally aligned along the twofold screw axis parallel to the c crystal axis forming polymeric-like columns, The 6-aminohexyl chain enters th e cavity of an adjacent cyclomaltoheptaose moiety in the column from t he secondary side and its extremity protrudes from the primary side of the latter. All the atoms of the chain exhibit high thermal motion.
