Materials Data on Sr(ZnGe)2 by Materials Project
Sr(ZnGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight equivalent Zn and eight equivalent Ge atoms. All Sr–Zn bond lengths are 3.46 Å. All Sr–Ge bond lengths are 3.40 Å. Zn is bonded to four equivalent Sr and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing ZnSr4Ge4 tetrahedra. All Zn–Ge bond lengths are 2.62 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Sr, four equivalent Zn, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
