Materials Data on YbMgAg by Materials Project
YbAgMg crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg is bonded to four equivalent Ag atoms to form a mixture of distorted edge and corner-sharing MgAg4 tetrahedra. There are a spread of Mg–Ag bond distances ranging from 2.87–2.91 Å. Yb is bonded in a 5-coordinate geometry to five equivalent Ag atoms. There are four shorter (3.19 Å) and one longer (3.21 Å) Yb–Ag bond lengths. Ag is bonded in a 9-coordinate geometry to four equivalent Mg and five equivalent Yb atoms.
