Materials Data on Yb2Ag7 by Materials Project
Yb2Ag7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to fourteen Ag atoms. There are a spread of Yb–Ag bond distances ranging from 3.20–3.40 Å. There are three inequivalent Ag sites. In the first Ag site, Ag is bonded in a 12-coordinate geometry to four equivalent Yb and eight Ag atoms. There are a spread of Ag–Ag bond distances ranging from 2.84–3.23 Å. In the second Ag site, Ag is bonded to four equivalent Yb and eight Ag atoms to form a mixture of edge, face, and corner-sharing AgYb4Ag8 cuboctahedra. There are a spread of Ag–Ag bond distances ranging from 2.75–2.77 Å. In the third Ag site, Ag is bonded to four equivalent Yb and eight Ag atoms to form a mixture of edge, face, and corner-sharing AgYb4Ag8 cuboctahedra.
