The material described by SrGe2 is Magnesium tetraboride-like structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 11-coordinate geometry to two equivalent Ge(2), three equivalent Ge(3), and six equivalent Ge(1) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to two equivalent Ge(3), three equivalent Ge(2), and four equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), one Ge(1), one Ge(2), and one Ge(3) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), one Ge(3), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), one Ge(2), and two equivalent Ge(1) atoms. is represented by the CIF file [CIF]
