Abstract:
The title compound, C17H38N4O3, is an asymmetric tetraazacyclododecane macrocycle with three pendant hydroxyisopropyl arms. Two of these arms are involved in hydrogen bonding internal to the macrocyclic ring while the third forms an intermolecular O-H⋯N hydrogen bond, leading to chains of molecules. © 2006 International Union of Crystallography All rights reserved.
