Materials Data on Sr(GeIr)2 by Materials Project
SrIr2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight equivalent Ir and eight equivalent Ge atoms. All Sr–Ir bond lengths are 3.44 Å. All Sr–Ge bond lengths are 3.31 Å. Ir is bonded to four equivalent Sr and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing IrSr4Ge4 tetrahedra. All Ir–Ge bond lengths are 2.49 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Sr, four equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.81 Å.
