Abstract

Ba3GaSb3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six Sb3- atoms to form distorted BaSb6 octahedra that share corners with six BaSb6 octahedra, corners with four equivalent GaSb4 tetrahedra, edges with twelve BaSb6 octahedra, and faces with two equivalent GaSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 9–17°. There are a spread of Ba–Sb bond distances ranging from 3.53–3.68 Å. In the second Ba2+ site, Ba2+ is bonded to six Sb3- atoms to form distorted BaSb6 octahedra that share corners with six BaSb6 octahedra, corners with four equivalent GaSb4 tetrahedra, edges with twelve BaSb6 octahedra, and faces with two equivalent GaSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 12–16°. There are a spread of Ba–Sb bond distances ranging from 3.53–3.72 Å. In the third Ba2+ site, Ba2+ is bonded to six Sb3- atoms to form distorted BaSb6 octahedra that share corners with six BaSb6 octahedra, corners with four equivalent GaSb4 tetrahedra, edges with twelve BaSb6 octahedra, and a faceface with one GaSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 10–24°. There are a spread of Ba–Sb bond distancesmore »« less
