Hydrothermal synthesis of a luminescent Europium(III) sulfate with three-dimensional chiral framework structure

The crystal structure and luminescent property of hydrothermally grown crystals of [NaEu(H2O)(SO4)2] (1) are reported. The crystal structure is composed of three kinds of right-handed helical chains, {EuOSO4}, {NaOSO4} and {EuONa}, which are connected together to form a three-dimensional framework structure via corner-shared polyhedra. The sharp peaks in the emission spectrum of 1 are assigned and analyzed. Crystal data: Trigonal, P3121, with image, image and image.
