The crystal structure described by Li7Ge2 crystallizes in the orthorhombic Cmmm space group. There are six inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to one Li(3), one Ge(1), and two equivalent Ge(2) atoms. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to four equivalent Ge(1) atoms. In the third Li site, Li(3) is bonded in a 8-coordinate geometry to four equivalent Li(1) and four equivalent Li(4) atoms. In the fourth Li site, Li(4) is bonded in a 4-coordinate geometry to two equivalent Li(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. In the fifth Li site, Li(5) is bonded in a 2-coordinate geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms. In the sixth Li site, Li(6) is bonded in a 1-coordinate geometry to two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted body-centered cubic geometry to two equivalent Li(1), two equivalent Li(2), two equivalent Li(4), and two equivalent Li(5) atoms. In the second Ge site, Ge(2) is bonded in a 12-coordinate geometry to two equivalent Li(4), two equivalent Li(5), four equivalent Li(1), and four equivalent Li(6) atoms. is represented by the CIF card [CIF]
