Crystal structure of [UO2(NH3)5]NO3·NH3.
Ontology highlight
ABSTRACT: Penta-ammine dioxide uranium(V) nitrate ammonia (1/1), [UO2(NH3)5]NO3·NH3, was obtained in the form of yellow crystals from the reaction of caesium uranyl nitrate, Cs[UO2(NO3)3], and uranium tetra-fluoride, UF4, in dry liquid ammonia. The [UO2]+ cation is coordinated by five ammine ligands. The resulting [UO2(NH3)5] coordination polyhedron is best described as a penta-gonal 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 mol-ecules, leading to a three-dimensional network.
