The new uranyl complex UO2(NO3)2[C5H10NC(O)NH10C5]2 has been synthesized and its structure was determined by single-crystal X-ray diffraction. Crystal data: C22H40N6O10U, monoclinic, space group P21/c, a = 11.151(3), b = 13.907(3), c = 10.067(2)A,β= 115.602(4)0,V = 1408.0(5) A3, Mr = 786.63, Z = 2, Dc = 1.855 g/cm3, F(000) = 772,μ = 5.827 mm-1, R = 0.0465 and wR = 0.1065 for 2916 observed reflections (I > 2σ(I)). The central uranyl ion is coordinated by six oxygen atoms, of which two are from the carbonyl groups of di-piperidin-1-yl-methanone molecules and the other four from two nitrate groups.
