The crystal structure described by Ba8Ge43 crystallizes in the trigonal R32 space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 14-coordinate geometry to one Ge(5), one Ge(6), three equivalent Ge(1), three equivalent Ge(3), three equivalent Ge(7), and three equivalent Ge(8) atoms. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and two equivalent Ge(9) atoms. In the third Ba site, Ba(3) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and two equivalent Ge(9) atoms. There are nine inequivalent Ge sites. In the first Ge site, Ge(9) is bonded to two equivalent Ba(2), two equivalent Ba(3), two equivalent Ge(1), and two equivalent Ge(3) atoms to form distorted GeBa4Ge4 tetrahedra that share corners with four equivalent Ge(9)Ba4Ge4 tetrahedra, corners with four equivalent Ge(4)Ba2Ge3 trigonal bipyramids, and faces with two equivalent Ge(4)Ba2Ge3 trigonal bipyramids. In the second Ge site, Ge(5) is bonded in a 5-coordinate geometry to one Ba(1), one Ge(5), and three equivalent Ge(1) atoms. In the third Ge site, Ge(6) is bonded in a 5-coordinate geometry to one Ba(1), one Ge(6), and three equivalent Ge(2) atoms. In the fourth Ge site, Ge(7) is bonded in a 5-coordinate geometry to one Ba(1), one Ge(2), one Ge(3), one Ge(4), and one Ge(7) atom. In the fifth Ge site, Ge(8) is bonded in a 5-coordinate geometry to one Ba(1), one Ge(1), one Ge(3), one Ge(4), and one Ge(8) atom. In the sixth Ge site, Ge(1) is bonded in a 7-coordinate geometry to one Ba(1), one Ba(2), one Ba(3), one Ge(4), one Ge(5), one Ge(8), and one Ge(9) atom. In the seventh Ge site, Ge(2) is bonded in a 5-coordinate geometry to one Ba(2), one Ba(3), one Ge(3), one Ge(6), and one Ge(7) atom. In the eighth Ge site, Ge(3) is bonded in a 7-coordinate geometry to one Ba(1), one Ba(2), one Ba(3), one Ge(2), one Ge(7), one Ge(8), and one Ge(9) atom. In the ninth Ge site, Ge(4) is bonded to one Ba(2), one Ba(3), one Ge(1), one Ge(7), and one Ge(8) atom to form distorted GeBa2Ge3 trigonal bipyramids that share corners with two equivalent Ge(9)Ba4Ge4 tetrahedra, corners with two equivalent Ge(4)Ba2Ge3 trigonal bipyramids, and  a faceface with one Ge(9)Ba4Ge4 tetrahedra. is represented by the CIF card [CIF]
