Materials Data on EuMgSn by Materials Project

MgEuSn crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg is bonded to four equivalent Sn atoms to form a mixture of distorted edge and corner-sharing MgSn4 tetrahedra. There are a spread of Mg–Sn bond distances ranging from 2.95–3.05 Å. Eu is bonded in a 5-coordinate geometry to five equivalent Sn atoms. There are a spread of Eu–Sn bond distances ranging from 3.38–3.48 Å. Sn is bonded in a 9-coordinate geometry to four equivalent Mg and five equivalent Eu atoms.
