The title compound (conveniently abbreviated Eu(TAN)3·dipy) has been crystallized from a chloroform/2-propanol solvent mixture to give two different forms. These have been characterized by luminescence spectroscopy and by X-ray diffraction. The two forms have different coordination polyhedra which means that they are structural isomers. One of them is best described as bicapped trigonal prismatic and the other, which contains two slightly different molecules, as square antiprismatic.
