Abstract

Ca3AlSb3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six Sb3- atoms to form CaSb6 octahedra that share corners with seven equivalent CaSb6 octahedra, corners with three equivalent AlSb4 tetrahedra, corners with six equivalent CaSb5 trigonal bipyramids, edges with four equivalent CaSb6 octahedra, edges with two equivalent AlSb4 tetrahedra, an edgeedge with one CaSb5 trigonal bipyramid, a faceface with one CaSb6 octahedra, and a faceface with one CaSb5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 38–54°. There are a spread of Ca–Sb bond distances ranging from 3.18–3.43 Å. In the second Ca2+ site, Ca2+ is bonded to six Sb3- atoms to form CaSb6 octahedra that share corners with seven equivalent CaSb6 octahedra, corners with three equivalent AlSb4 tetrahedra, corners with three equivalent CaSb5 trigonal bipyramids, edges with four equivalent CaSb6 octahedra, edges with three equivalent AlSb4 tetrahedra, edges with three equivalent CaSb5 trigonal bipyramids, and a faceface with one CaSb6 octahedra. The corner-sharing octahedra tilt angles range from 38–54°. There are a spread of Ca–Sb bond distances ranging from 3.18–3.41 Å. In the third Ca2+ site, Ca2+ is bonded tomore »« less
