The organically‐templated uranyl selenite, (H 2 en)[(UO 2 )(SeO 3 )(HSeO 3 )](NO 3 ) · 0.5H 2 O ( 1 ) (en = 1,2‐ethylenediamine) was synthesized and characterized by elemental analyses, IR spectroscopy, TG, and single‐crystal X‐ray diffraction. Compound 1 crystallizes in the orthorhombic system, space group Pbca , with a = 13.170(3) Å, b = 11.055(2) Å, c = 18.009(4) Å, V = 2621.8(9) Å 3 , M = 1316.19, Z = 4, D cal = 3.334 g · cm –3 , μ (Mo‐ K α ) = 17.998 mm –1 , GOF = 1.059, R 1 = 0.0263, wR 2 = 0.0532 [ I >2 σ ( I )]. The X‐ray diffraction analysis reveals that compound 1 has a three‐dimensional (3D) supramolecular structure. It contains negatively charged [UO 2 (HSeO 3 )(SeO 3 )] – inorganic anion layers and is balanced by [H 2 en] 2+ cations and NO 3 – anions located in the interlayers. Furthermore, the photoluminescence properties of 1 were investigated.
