Abstract

Pb3U11O36 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are six inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent UO6 octahedra, corners with two equivalent PbO7 pentagonal bipyramids, edges with two equivalent UO6 octahedra, and edges with two equivalent UO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 33°. There are a spread of U–O bond distances ranging from 1.85–2.52 Å. In the second U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two UO6 octahedra, a cornercorner with one UO7 pentagonal bipyramid, corners with two equivalent PbO7 pentagonal bipyramids, an edgeedge with one UO6 octahedra, and edges with two UO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 35–48°. There are a spread of U–O bond distances ranging from 1.86–2.48 Å. In the third U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with four UO6 octahedra, a cornercorner with one UO7 pentagonal bipyramid, an edgeedge with one UO6 octahedra, an edgeedge with one UO7 pentagonalmore » bipyramid, and an edgeedge with one PbO7 pentagonal bipyramid.

In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to three U6+ atoms. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to three U6+ atoms. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to two U6+ and one Pb2+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and two Pb2+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted trigonal planar geometry to three U6+ atoms. In the fourteenth O2- site, O2- is bonded in a linear geometry to two U6+ atoms. In the fifteenth O2- site, O2- is bonded in a 1-coordinate geometry to two U6+ and one Pb2+ atom.
