Materials Data on YbZnGa by Materials Project

YbZnGa crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Yb is bonded in a 12-coordinate geometry to six equivalent Zn and six equivalent Ga atoms. There are a spread of Yb–Zn bond distances ranging from 3.08–3.27 Å. There are a spread of Yb–Ga bond distances ranging from 3.11–3.27 Å. Zn is bonded in a 10-coordinate geometry to six equivalent Yb, one Zn, and three equivalent Ga atoms. The Zn–Zn bond length is 2.64 Å. There are two shorter (2.61 Å) and one longer (2.90 Å) Zn–Ga bond lengths. Ga is bonded in a 10-coordinate geometry to six equivalent Yb, three equivalent Zn, and one Ga atom. The Ga–Ga bond length is 2.62 Å.
