Title: Materials Data on Tb3SbO7 by Materials Project

Abstract

Tb3SbO7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to seven O2- atoms to form distorted TbO7 pentagonal bipyramids that share corners with two equivalent SbO6 octahedra, corners with three equivalent TbO7 pentagonal bipyramids, edges with two equivalent SbO6 octahedra, and edges with two equivalent TbO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 42°. There are a spread of Tb–O bond distances ranging from 2.23–2.62 Å. In the second Tb3+ site, Tb3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.36 Å) and four longer (2.69 Å) Tb–O bond lengths. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra, corners with four equivalent TbO7 pentagonal bipyramids, and edges with four equivalent TbO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. All Sb–O bond lengths are 2.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four Tb3+ atoms to form a mixture of corner and edge-sharing OTb4 tetrahedra. In the second O2- site, O2- is bonded inmore » a 4-coordinate geometry to three Tb3+ and one Sb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Tb3+ and two equivalent Sb5+ atoms.« less
