SrIr2Ge2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 16-coordinate geometry to eight equivalent Ir(1) and eight equivalent Ge(1) atoms. Ir(1) is bonded to four equivalent Sr(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge, face, and corner-sharing IrSr4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), four equivalent Ir(1), and one Ge(1) atom.
