Prossima pubblicazione.

Referenza:
▪ Plášil, J., Kampf, A.R., Škoda, R., Čejka, J. (2018): Structure of Nollmotzite, Mg[UV(UVIO2)2O4F3]·4H2O, the first natural uranium-oxide containing fluorine. Acta Crystallographica, B74, (in press):

Synopsis:
The twinned structure of the new uranium-oxide mineral was refined from the X-ray diffraction data and was found to contain fluorine and pentavalent uranium. The presence of pentavalent uranium is indicative of the reducing conditions under which the mineral formed. Nollmotzite is the first naturally occurring uranium-oxide mineral that contains fluorine.
