Title: Materials Data on MgGa5 by Materials Project

Abstract

MgGa5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mg is bonded to twelve Ga atoms to form MgGa12 cuboctahedra that share edges with six equivalent MgGa12 cuboctahedra, edges with twelve equivalent GaMg2Ga10 cuboctahedra, faces with two equivalent MgGa12 cuboctahedra, and faces with twelve equivalent GaMg2Ga10 cuboctahedra. There are six shorter (2.95 Å) and six longer (3.08 Å) Mg–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded to two equivalent Mg and ten Ga atoms to form distorted GaMg2Ga10 cuboctahedra that share corners with eighteen equivalent GaMg2Ga10 cuboctahedra, edges with four equivalent MgGa12 cuboctahedra, edges with six equivalent GaMg2Ga10 cuboctahedra, faces with four equivalent MgGa12 cuboctahedra, and faces with eight equivalent GaMg2Ga10 cuboctahedra. There are a spread of Ga–Ga bond distances ranging from 2.93–3.06 Å. In the second Ga site, Ga is bonded in a distorted trigonal planar geometry to three equivalent Mg and six equivalent Ga atoms.
