Materials Data on Ba3SrSn12 by Materials Project
Abstract
Ba3SrSn12 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are three inequivalent Ba sites. In the first Ba site, Ba is bonded to twelve Sn atoms to form distorted BaSn12 cuboctahedra that share corners with two equivalent BaSn12 cuboctahedra, corners with four equivalent SrSn12 cuboctahedra, and faces with eight BaSn12 cuboctahedra. There are a spread of Ba–Sn bond distances ranging from 3.63–3.76 Å. In the second Ba site, Ba is bonded to twelve Sn atoms to form distorted BaSn12 cuboctahedra that share corners with six BaSn12 cuboctahedra, faces with four BaSn12 cuboctahedra, and faces with four equivalent SrSn12 cuboctahedra. There are a spread of Ba–Sn bond distances ranging from 3.62–3.74 Å. In the third Ba site, Ba is bonded to twelve Sn atoms to form distorted BaSn12 cuboctahedra that share corners with six BaSn12 cuboctahedra, faces with two equivalent SrSn12 cuboctahedra, and faces with six BaSn12 cuboctahedra. There are a spread of Ba–Sn bond distances ranging from 3.62–3.76 Å. Sr is bonded to twelve Sn atoms to form distorted SrSn12 cuboctahedra that share corners with two equivalent SrSn12 cuboctahedra, corners with four equivalent BaSn12 cuboctahedra, faces with two equivalent SrSn12 cuboctahedra, and faces with six BaSn12more »
