Interaction of uranium hexafluoride with ammonia

Reactions of ThX4 (X=F, Cl, Br, I) with Liquid Ammonia‐Crystal Structures and a Theoretical Study of Ammine Thorium(IV) Halide Ammoniates

“…Most of the research in the field of the early actinoids in liquid ammonia solution was conducted in the 60s and 70s of the last century. However, the analytical capabilities were not always convenient for the characterization of such types of compounds [11‐26] . Nowadays, single crystal X‐ray diffraction, especially at low temperatures, affords a suitable analytical method for the investigation of compounds that are often moisture as well as temperature sensitive.…”

UF6 and UF4 in Liquid Ammonia: [UF7(NH3)]3− and [UF4(NH3)4]

“…Obviously, a more direct pathway towards uranium nitrides could be by reactions between UF 6 and NH 3 . Studies of the reaction of UF 6 with NH 3 were first reported 51 years ago,12, 13 and the products were assumed to be UF 5 and NH 4 UF 5 based on observation of their colors and elemental analysis data. Burk and Berthold tried to elucidate the nature of the reactions of green salt with ammonia at various temperatures and arrived at the conclusion that UF 4 is insoluble in liquid ammonia 14.…”

Metal Derivatives of Arylazopyrazolone Compounds. VI. Molarity Quotients of Azo Derivatives of 1-Phenyl-3-methyl-5-thiopyrazolone

“…This is a mononitrosyl similar to those previously obtained from the reaction between nitric oxide and dicarbonylbis (triphenylphosphine) nickel. 6 Thus the only nitrosyl nickel complexes which result from the reactions between Ni(0) complexes and nitric oxide are of the type [NiNO]+.…”
