(Nitrato-κ2O,O′)bis(triethanolamine-κ4N,O,O′,O′′)lanthanum(III) dinitrate

Abstract

The title compound, [La(NO3)(C6H15NO3)2](NO3)2, contains a network of [La(NO3)(C6H15NO3)2]2+ cations and nitrate counter-ions. The crystal packing is influenced by cation-to-anion O-H...O hydrogen bonds, resulting in a structure with one-dimensional character. The ten-coordinate La atom and a nitrate anion have site symmetry 2. The fact that triethanolamine can bind to such diverse cations as Li+ and La3+ militates against possible applications that require selective binding of ligand to metal.
