Abstract

Sm3OsO7 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are six inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sm–O bond distances ranging from 2.35–2.59 Å. In the second Sm3+ site, Sm3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sm–O bond distances ranging from 2.37–2.56 Å. In the third Sm3+ site, Sm3+ is bonded to seven O2- atoms to form SmO7 pentagonal bipyramids that share corners with two OsO6 octahedra, corners with two equivalent SmO7 pentagonal bipyramids, and edges with two OsO6 octahedra. The corner-sharing octahedra tilt angles range from 39–45°. There are a spread of Sm–O bond distances ranging from 2.27–2.55 Å. In the fourth Sm3+ site, Sm3+ is bonded to seven O2- atoms to form SmO7 pentagonal bipyramids that share corners with two OsO6 octahedra, corners with two equivalent SmO7 pentagonal bipyramids, and edges with two OsO6 octahedra.
