Abstract

U5P3Se2 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent U sites. In the first U site, U is bonded to three P and three Se atoms to form a mixture of edge and corner-sharing UP3Se3 octahedra. The corner-sharing octahedra tilt angles range from 2–3°. There are a spread of U–P bond distances ranging from 2.76–2.82 Å. There are two shorter (2.84 Å) and one longer (2.86 Å) U–Se bond lengths. In the second U site, U is bonded to four P and two equivalent Se atoms to form a mixture of edge and corner-sharing UP4Se2 octahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are a spread of U–P bond distances ranging from 2.75–2.81 Å. There are one shorter (2.87 Å) and one longer (2.88 Å) U–Se bond lengths. In the third U site, U is bonded to four P and two equivalent Se atoms to form UP4Se2 octahedra that share corners with six UP4Se2 octahedra and edges with twelve UP3Se3 octahedra. The corner-sharing octahedra tilt angles range from 1–2°. There are two shorter (2.79 Å) and two longer (2.81 Å) U–P bond lengths. Both U–Se bond lengthsmore »« less
