Materials Data on EuMgSi by Materials Project
Abstract
EuMgSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg2+ is bonded to four equivalent Si4- atoms to form MgSi4 tetrahedra that share corners with eight equivalent MgSi4 tetrahedra, corners with eight equivalent EuSi5 trigonal bipyramids, edges with two equivalent MgSi4 tetrahedra, and edges with six equivalent EuSi5 trigonal bipyramids. There are a spread of Mg–Si bond distances ranging from 2.77–2.88 Å. Eu2+ is bonded to five equivalent Si4- atoms to form EuSi5 trigonal bipyramids that share corners with eight equivalent MgSi4 tetrahedra, corners with eight equivalent EuSi5 trigonal bipyramids, edges with six equivalent MgSi4 tetrahedra, and edges with six equivalent EuSi5 trigonal bipyramids. There are one shorter (3.17 Å) and four longer (3.23 Å) Eu–Si bond lengths. Si4- is bonded in a 9-coordinate geometry to four equivalent Mg2+ and five equivalent Eu2+ atoms.
