Bis{ N -[bis(pyrrolidin-1-yl)phosphoryl]-2,2,2-trichloroacetamide}dinitratodioxidouranium(VI)

The crystal structure of the title compound, [U(NO3)2O2(C10H17Cl3N3O2P)2], is composed of centrosymmetric [UO2(L)2(NO3)2] molecules {L is N-[bis(pyrrolidin-1-yl)phosphoryl]-2,2,2-trichloroacetamide, C10H17Cl3N3O2P}. The UVI ion, located on an inversion center, is eight-coordinated with axial oxido ligands and six equatorial oxygen atoms of the phosphoryl and nitrate groups in a slightly distorted hexagonal-bipyramidal geometry. One of the pyrrolidine fragments in the ligand is disordered over two conformation (occupancy ratio 0.58:0.42). Intramolecular N—H...O hydrogen bonds between the amine and nitrate groups are found.
