Title: Materials Data on RbBi3Se5 by Materials Project

Abstract

RbBi3Se5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.51–3.89 Å. There are three inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing BiSe6 octahedra. The corner-sharing octahedra tilt angles range from 4–10°. There are a spread of Bi–Se bond distances ranging from 2.92–3.01 Å. In the second Bi3+ site, Bi3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing BiSe6 octahedra. The corner-sharing octahedra tilt angles range from 4–10°. There are a spread of Bi–Se bond distances ranging from 2.81–3.29 Å. In the third Bi3+ site, Bi3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing BiSe6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are a spread of Bi–Se bond distances ranging from 2.80–3.19 Å. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to one Rb1+ and four Bi3+ atoms to form SeRbBi4 trigonal bipyramids that share a cornercorner with one SeBi6 octahedra,more » corners with three equivalent SeRb2Bi3 square pyramids, corners with two equivalent SeRbBi4 trigonal bipyramids, edges with two equivalent SeBi6 octahedra, and edges with two equivalent SeRbBi4 trigonal bipyramids. The corner-sharing octahedral tilt angles are 2°. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Rb1+ and three Bi3+ atoms. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two equivalent Bi3+ atoms. In the fourth Se2- site, Se2- is bonded to six Bi3+ atoms to form SeBi6 octahedra that share corners with two equivalent SeRb2Bi3 square pyramids, a cornercorner with one SeRbBi4 trigonal bipyramid, edges with four equivalent SeBi6 octahedra, edges with three equivalent SeRb2Bi3 square pyramids, and edges with two equivalent SeRbBi4 trigonal bipyramids. In the fifth Se2- site, Se2- is bonded to two equivalent Rb1+ and three Bi3+ atoms to form SeRb2Bi3 square pyramids that share corners with two equivalent SeBi6 octahedra, corners with three equivalent SeRbBi4 trigonal bipyramids, edges with three equivalent SeBi6 octahedra, and edges with two equivalent SeRb2Bi3 square pyramids. The corner-sharing octahedral tilt angles are 7°.« less
