The crystal structure of 6I-(6-aminohexyl)amino-6I-deoxycyclomaltoheptaose.
The monosubstituted cyclomaltoheptaose derivative, 6I-(6-aminohexyl)amino-6I-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) A, V = 7636.6(8) A3 and Z = 4. The macrocycles are spirally aligned along the twofold screw axis parallel to the c crystal axis forming polymeric-like columns. The 6-aminohexyl chain enters the cavity of an adjacent cyclomaltoheptaose moiety in the column from the secondary side and its extremity protrudes from the primary side of the latter. All the atoms of the chain exhibit high thermal motion.
