Materials Data on SrMg6Zr by Materials Project
Abstract
SrMg6Zr is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sr is bonded to ten Mg and two equivalent Zr atoms to form distorted SrMg10Zr2 cuboctahedra that share corners with four equivalent MgSr2Mg10 cuboctahedra, corners with six equivalent SrMg10Zr2 cuboctahedra, edges with two equivalent MgSr2Mg10 cuboctahedra, edges with four equivalent ZrSr2Mg10 cuboctahedra, faces with two equivalent SrMg10Zr2 cuboctahedra, faces with two equivalent ZrSr2Mg10 cuboctahedra, and faces with eight MgMg10Zr2 cuboctahedra. There are a spread of Sr–Mg bond distances ranging from 3.29–3.48 Å. Both Sr–Zr bond lengths are 3.54 Å. There are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 11-coordinate geometry to two equivalent Sr, seven Mg, and two equivalent Zr atoms. There are a spread of Mg–Mg bond distances ranging from 3.18–3.38 Å. There are one shorter (3.11 Å) and one longer (3.49 Å) Mg–Zr bond lengths. In the second Mg site, Mg is bonded to ten Mg and two equivalent Zr atoms to form MgMg10Zr2 cuboctahedra that share corners with four equivalent ZrSr2Mg10 cuboctahedra, corners with six equivalent MgMg10Zr2 cuboctahedra, edges with two equivalent ZrSr2Mg10 cuboctahedra, edges with four equivalent MgSr2Mg10 cuboctahedra, facesmore »
