The Gd atom in the title compound, [Gd(C33H39N11)]Cl3·3H2O, lies on a position of 32 point symmetry and exhibits a tricapped trigonal prismatic coordination geometry. A twofold rotation axis passes through the coordinated N atom and the opposite C atom of the pyridyl ring of the ligand, while a threefold rotation axis passes through the aliphatic N atom. The Cl atom and O atom of the uncoordinated water mol­ecule both lie on twofold rotation axes. [ABSTRACT FROM AUTHOR]
