Nollmotzite, Mg[U V (U VI O 2 ) 2 O 4 F 3 ]·4H 2 O, the first natural uranium oxide containing fluorine.
Acta Crystallographica Section B, Structural Science, Crystal Engineering and Materials 2018 August 2
Nollmotzite (IMA2017-100), Mg[UV (UVI O2 )2 F3 O4 ](H2 O)4 , is a new uranium oxide fluoride mineral found in the Clara mine, Black Forest Mountains, Germany. Electron microprobe analysis provided the empirical formula (Mg1.06 Cu0.02 )Σ1.08 [UV (UVI O2 )2 O3.85 F3.15 ][(H2 O)3.69 (OH)0.31 ]Σ4.00 based on three U and 15 O + F atoms per formula unit. Nollmotzite is monoclinic, space group Cm, with a = 7.1015 (12) Å, b = 11.7489 (17) Å, c = 8.1954 (14) Å, β = 98.087 (14)°, V = 676.98 (19) Å3 and Z = 2. The crystal structure [twinned by reticular merohedry; refined to R = 0.0369 with GoF = 1.09 for 1527 unique observed reflections, I > 3σ(I)] is based upon [UV (UVI O2 )2 F3 O4 ]2- sheets of β-U3 O8 topology and contains an interlayer with MgF2 (H2 O)4 octahedra. Adjacent sheets are linked through F-Mg-F bonds, as well as via hydrogen bonds. The presence of fluorine and pentavalent uranium in the structure of nollmotzite has potentially important implications for the safe disposal of nuclear waste.
