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

Abstract
The crystal structure of the title compound, [U(NO3)(2)O-2-(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 U VI 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 center dot center dot center dot O hydrogen bonds between the amine and nitrate groups are found.
