Title: Materials Data on SrMg6Sn by Materials Project

Abstract

SrMg6Sn crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sr is bonded to ten Mg and two equivalent Sn atoms to form SrMg10Sn2 cuboctahedra that share corners with four equivalent MgSr2Mg10 cuboctahedra, corners with six equivalent SrMg10Sn2 cuboctahedra, edges with two equivalent MgSr2Mg10 cuboctahedra, faces with two equivalent SrMg10Sn2 cuboctahedra, and faces with eight MgMg10Sn2 cuboctahedra. There are a spread of Sr–Mg bond distances ranging from 3.38–3.44 Å. Both Sr–Sn bond lengths are 3.29 Å. There are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 3-coordinate geometry to two equivalent Sr, six Mg, and one Sn atom. There are a spread of Mg–Mg bond distances ranging from 3.18–3.41 Å. The Mg–Sn bond length is 3.18 Å. In the second Mg site, Mg is bonded to ten Mg and two equivalent Sn atoms to form distorted MgMg10Sn2 cuboctahedra that share corners with six equivalent MgMg10Sn2 cuboctahedra, edges with four equivalent MgSr2Mg10 cuboctahedra, faces with four MgMg10Sn2 cuboctahedra, and faces with six equivalent SrMg10Sn2 cuboctahedra. All Mg–Mg bond lengths are 3.29 Å. Both Mg–Sn bond lengths are 3.44 Å. In the third Mg site, Mg is bonded in a 12-coordinate geometry to twomore » equivalent Sr, eight Mg, and two equivalent Sn atoms. There are a spread of Mg–Mg bond distances ranging from 3.30–3.50 Å. Both Mg–Sn bond lengths are 3.24 Å. In the fourth Mg site, Mg is bonded to two equivalent Sr and ten Mg atoms to form distorted MgSr2Mg10 cuboctahedra that share corners with four equivalent SrMg10Sn2 cuboctahedra, corners with six equivalent MgSr2Mg10 cuboctahedra, edges with two equivalent SrMg10Sn2 cuboctahedra, edges with four equivalent MgMg10Sn2 cuboctahedra, faces with two equivalent SrMg10Sn2 cuboctahedra, and faces with four MgMg10Sn2 cuboctahedra. Sn is bonded in a 10-coordinate geometry to two equivalent Sr and eight Mg atoms.« less
