Reinvestigation of the crystal structure of kasolite, Pb[(UO2)(SiO4)](H2O), an important alteration product of uraninite, UO2-x.
Original language description
The crystal structure of kasolite, Pb[(UO2)(SiO4)](H2O), Z=4, monoclinic, with a=6.7050(3), b=6.9257(2), c=13.2857(5)A, b=105.064(4)°, V=595.74(3) A3, the space group P21/c, has been solved by charge-flipping method and refined by the full-matrix least-squares techniques to an agreement factor(Robs) of 2.2% for 1243 unique observed reflections. The crystal structure of kasolite contains 1 unique U6+ position that is part of a nearly linear uranyl ion (UO2)2+, coordinated in the equatorial plane by fiveO ligands, forming pentagonal bipyramid. The uranyl pentagonal bipyramid s share edges to form chains parallel to [010]. The additional edge of uranyl polyhedra is shared by silicate tetrahedra to form sheets parallel to (100). There is one unique position of Pb2+ in the interlayer. O ligands and 1 (H2O) non-transformer group coordinate Pb2+ exhibiting [2 + 6] coordination.
