Abstract: | The organically‐templated uranyl selenite, (H2en)[(UO2)(SeO3)(HSeO3)](NO3) · 0.5H2O ( 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) Å3, M = 1316.19, Z = 4, Dcal = 3.334 g · cm–3, μ(Mo‐Kα) = 17.998 mm–1, GOF = 1.059, R1 = 0.0263, wR2 = 0.0532 [I>2σ(I)]. The X‐ray diffraction analysis reveals that compound 1 has a three‐dimensional (3D) supramolecular structure. It contains negatively charged [UO2(HSeO3)(SeO3)]– inorganic anion layers and is balanced by [H2en]2+ cations and NO3– anions located in the interlayers. Furthermore, the photoluminescence properties of 1 were investigated. |
