Title: Materials Data on CaMg2 by Materials Project

Abstract

Mg2Ca crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ca is bonded to two equivalent Ca and ten equivalent Mg atoms to form CaCa2Mg10 cuboctahedra that share corners with six equivalent CaCa2Mg10 cuboctahedra, corners with twelve equivalent MgCa5Mg7 cuboctahedra, edges with eight equivalent MgCa5Mg7 cuboctahedra, edges with ten equivalent CaCa2Mg10 cuboctahedra, faces with four equivalent CaCa2Mg10 cuboctahedra, and faces with sixteen equivalent MgCa5Mg7 cuboctahedra. Both Ca–Ca bond lengths are 3.41 Å. There are a spread of Ca–Mg bond distances ranging from 3.36–3.53 Å. Mg is bonded to five equivalent Ca and seven equivalent Mg atoms to form distorted MgCa5Mg7 cuboctahedra that share corners with six equivalent CaCa2Mg10 cuboctahedra, corners with twelve equivalent MgCa5Mg7 cuboctahedra, edges with four equivalent CaCa2Mg10 cuboctahedra, edges with fourteen equivalent MgCa5Mg7 cuboctahedra, faces with eight equivalent CaCa2Mg10 cuboctahedra, and faces with twelve equivalent MgCa5Mg7 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.38–3.47 Å.
