A new uranium(VI) monophosphate with a layered structure: Ba{sub 3}[UO{sub 2}(PO{sub 4})(PO{sub 3}(OH))]{sub 2}{center_dot}xH{sub 2}O (x {approx} 0.4)

A new uranium(VI) phosphate containing barium has been synthesized hydrothermally: Ba{sub 3}[UO{sub 2}(PO{sub 4})(PO{sub 3}(OH))]{sub 2}{center_dot}xH{sub 2}O (x {approx} 0.4). The structure determination and refinement have been performed using single-crystal X-ray diffraction in the P2{sub 1}/c space group with Z = 2. The presence of hydroxyl groups and water molecules in the structure has been evidenced by IR and TGA studies. The U-P-O host lattice consists of puckered layers resulting from the connection of UO{sub 7} pentagonal bipyramids and monophosphate groups; the barium cations are distributed over two sites between these layers.
