The crystal structure described by SrCrGe2 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 7-coordinate geometry to four equivalent Cr(2), two equivalent Ge(4), two equivalent Ge(5), and three equivalent Ge(2) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to three equivalent Cr(2), one Ge(2), one Ge(3), two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 6-coordinate geometry to two equivalent Cr(2), two equivalent Ge(2), two equivalent Ge(3), and two equivalent Ge(5) atoms. In the second Cr site, Cr(2) is bonded in a 12-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), one Cr(1), one Ge(1), one Ge(2), one Ge(3), one Ge(4), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 6-coordinate geometry to two equivalent Sr(2), two equivalent Cr(1), and two equivalent Cr(2) atoms. In the second Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Sr(1), four equivalent Sr(2), two equivalent Cr(2), and one Ge(4) atom. In the third Ge site, Ge(5) is bonded in a 7-coordinate geometry to one Sr(1), two equivalent Sr(2), one Cr(1), two equivalent Cr(2), and one Ge(5) atom. In the fourth Ge site, Ge(1) is bonded in a 2-coordinate geometry to four equivalent Sr(2) and two equivalent Cr(2) atoms.
