Abstract :
Structures of complexes of hexa(ethylene glycol) with cyclomaltohexaose (α-CD) and that of tetra(ethylene glycol) dibromide with α-CD have been determined by X-ray diffraction studies. α-CDs form columns in a head-to-head (the side of secondary hydroxyl groups) and tail-to-tail (the side of primary hydroxyl groups) fashion. Ethylene glycol chains are included in channels formed by α-CDs.
