The crystal structure of uranyl-oxide mineral schoepite, [(UO2 )4 O(OH)6 ](H2 O)6, revisited

Popis výsledku v původním jazyce

New single-crystal X-ray diffraction experiments have revealed that the crystal structure of schoepite, one of the more common U-oxide minerals, is centrosymmetric, rather than acentric as reported in the past. Its structure was solved by charge-flipping algorithm and refined for 4662 unique reflections collected using microfocus X-ray source. Schoepite structure, in line with its previous determination, is based upon U–O–OH sheets of the fourmarierite topology and an interlayer filled only by molecular H2O. The complexity calculations show that the difference in complexity values between sch oepite and metaschoepite are much smaller then considered previously. Such small difference is in line with the easy transformation of schoepite to metaschoepite under ambient conditions and a joint occurrence of both minerals.
