Materials Data on Ba5Sb4 by Materials Project
Ba5Sb4 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six Sb+2.50- atoms to form a mixture of face and corner-sharing BaSb6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Ba–Sb bond distances ranging from 3.57–3.71 Å. In the second Ba2+ site, Ba2+ is bonded to six Sb+2.50- atoms to form a mixture of distorted edge, face, and corner-sharing BaSb6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 38–46°. There are a spread of Ba–Sb bond distances ranging from 3.52–3.89 Å. There are two inequivalent Sb+2.50- sites. In the first Sb+2.50- site, Sb+2.50- is bonded to seven Ba2+ atoms to form a mixture of distorted edge and corner-sharing SbBa7 pentagonal bipyramids. In the second Sb+2.50- site, Sb+2.50- is bonded in a 9-coordinate geometry to eight Ba2+ and one Sb+2.50- atom. The Sb–Sb bond length is 2.93 Å.
