Materials Data on Mg14MnGa by Materials Project
Abstract
Mg14MnGa crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are ten inequivalent Mg sites. In the first Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent GaMg10Mn2 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with two equivalent MnMg10Ga2 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.13–3.20 Å. In the second Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent MnMg10Ga2 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with two equivalent GaMg10Mn2 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.13–3.21 Å. In the third Mg site, Mg is bonded to eight Mg, two equivalent Mn, and two equivalent Ga atoms to form distorted MgMg8Mn2Ga2 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with two equivalent MnMg10Ga2 cuboctahedra, edges with two equivalent GaMg10Mn2 cuboctahedra, edges with fourteen MgMg8Mn2Ga2 cuboctahedra, faces with two equivalent MnMg10Ga2 cuboctahedra, faces with two equivalent GaMg10Mn2 cuboctahedra, and faces with sixteen MgMg8Mn2Ga2 cuboctahedra.more »
