Abstract

Sr3U11O36 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to seven O2- atoms to form distorted SrO7 hexagonal pyramids that share corners with two equivalent UO6 octahedra, corners with two equivalent UO7 pentagonal bipyramids, edges with two equivalent UO6 octahedra, and edges with two equivalent SrO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 40°. There are a spread of Sr–O bond distances ranging from 2.46–2.67 Å. In the second Sr2+ site, Sr2+ is bonded to seven O2- atoms to form distorted SrO7 pentagonal bipyramids that share corners with two UO6 octahedra, corners with two equivalent UO7 pentagonal bipyramids, an edgeedge with one SrO7 hexagonal pyramid, edges with two UO6 octahedra, and an edgeedge with one UO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 38–41°. There are a spread of Sr–O bond distances ranging from 2.45–2.67 Å. There are six inequivalent U6+ sites.
