Crystal structure of [UO(2)(NH(3))(5)]NO(3)·NH(3)

Penta­ammine dioxide uranium(V) nitrate ammonia (1/1), [UO(2)(NH(3))(5)]NO(3)·NH(3), was obtained in the form of yellow crystals from the reaction of caesium uranyl nitrate, Cs[UO(2)(NO(3))(3)], and uranium tetra­fluoride, UF(4), in dry liquid ammonia. The [UO(2)](+) cation is coordinated by five ammine ligands. The resulting [UO(2)(NH(3))(5)] coordination polyhedron is best described as a penta­gonal bipyramid with the O atoms forming the apices. In the crystal, numerous N—H⋯N and N—H⋯O hydrogen bonds are present between the cation, anion and solvent mol­ecules, leading to a three-dimensional network.
