Abstract: The title complex crystallizes in triclinic, space group P1 with Z = 2.Lattice parameters are:a=8.468(2),b=8.787(2),c=16.674(4)Å,α=74.91(4)°,β=82.45(3)°,γ=69.84 (2)°, V=1123.4 Å3.The structure was solved by Patterson and Fourier techniques and refined by full-matrix least-squares to R=0.032 based on 4300 observed reflections.The linear uranyl group is perpendicular to a equatorial plane formed by six oxygen atoms, of which two from two water molecules, four from two bidentate nitrate groups.The coordination polyhedron takes a slight distored hexagonal bipyramid arrangement.The neutral UO2(NO3)2(H2O)2 units connect with crown ether by hydrogen bonding through intermediary water molecules.
