Materials Data on Sr(CdGe)2 by Materials Project
Sr(CdGe)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 Cd and eight equivalent Ge atoms. All Sr–Cd bond lengths are 3.74 Å. All Sr–Ge bond lengths are 3.48 Å. Cd is bonded to four equivalent Sr and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing CdSr4Ge4 tetrahedra. All Cd–Ge bond lengths are 2.84 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Sr, four equivalent Cd, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
