Materials Data on Ba(ZnGe)2 by Materials Project
Ba(ZnGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight equivalent Zn and eight equivalent Ge atoms. All Ba–Zn bond lengths are 3.52 Å. All Ba–Ge bond lengths are 3.50 Å. Zn is bonded to four equivalent Ba and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing ZnBa4Ge4 tetrahedra. All Zn–Ge bond lengths are 2.66 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ba, four equivalent Zn, and one Ge atom. The Ge–Ge bond length is 2.65 Å.
