Thermal expansion of metatorbernite, Cu(UO2)2(PO4)2(H2O)8 (1), and metazeunerite, Cu(UO2)2(AsO4)2(H2O)8 (2), has been investigated using single-crystal and powder X-ray diffraction. Both minerals are prone to dehydration, which proceeds already at am

A combination of neutron powder diffraction and ab initio random structure searching was used to locate hydrogen positions in the crystal structure of metatorbernite [Cu(UO2)2(PO4)2·8H2O], a common autunite mineral that shows promise for uranium rem
