The hybrid organic‐inorganic uranyl selenate, [K@(C 10 H 20 O 5 )][(UO 2 )(SeO 4 )(HSeO 4 )(H 2 O)] ( I ), was prepared by isothermal evaporation from aqueous solutions. The crystal structure of I [orthorhombic, Pnma , a = 15.386(3), b = 10.771(2), c = 13.239(3) Å, V = 2194.0(7) Å 3 , Z = 4, R 1 = 0.042] is based upon complex 15‐crown‐5‐ether‐uranyl‐selenate polymeric units consisting of uranyl selenate chains decorated by [K@(15‐crown‐5)] + complexes via strong ionic K + –O bonds. The 1D hybrid units are packed in a parquetted‐like fashion and connected to each other by hydrogen bonds and residual van der Waals interactions.
