Materials Data on Yb(AlGa)2 by Materials Project
YbAl2Ga2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to eight equivalent Ga and eight equivalent Al atoms. All Yb–Ga bond lengths are 3.25 Å. All Yb–Al bond lengths are 3.46 Å. Ga is bonded in a 9-coordinate geometry to four equivalent Yb, one Ga, and four equivalent Al atoms. The Ga–Ga bond length is 2.46 Å. All Ga–Al bond lengths are 2.60 Å. Al is bonded to four equivalent Yb and four equivalent Ga atoms to form a mixture of distorted face, edge, and corner-sharing AlYb4Ga4 tetrahedra.
