Abstract

In the title compound, [UO(2)L(2)(NO(3))(2)] {L = N-{bis-[meth-yl(phen-yl)amino]phosphor-yl}-2,2,2-trichloro-acetamide, C(16)H(17)Cl(3)N(3)O(2)P}, the U(VI) ions are eight-coordinated by axial oxido ligands and six equatorial O atoms from the phosphoryl and nitrate groups in a distorted hexa-gonal-bipyramidal geometry. There are disordered fragments in the two coordinating L ligands: the trichloro-methyl group is rotationally disordered between two orientations [occupancy ratio 0.567 (15):0.433 (15)] in one ligand, and a meth-yl(phen-yl)amine fragment is disordered over two conformations [occupancy ratio 0.60 (4):0.40 (4)] in the other ligand. In the crystal structure, intra-molecular N-H⋯O hydrogen bonds between the amine and nitrate groups are observed.
