Materials Data on Ca(ZnGe)2 by Materials Project
Ca(ZnGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ca is bonded in a 8-coordinate geometry to eight equivalent Zn and eight equivalent Ge atoms. All Ca–Zn bond lengths are 3.44 Å. All Ca–Ge bond lengths are 3.31 Å. Zn is bonded to four equivalent Ca and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing ZnCa4Ge4 tetrahedra. All Zn–Ge bond lengths are 2.58 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ca, four equivalent Zn, and one Ge atom. The Ge–Ge bond length is 2.51 Å.
