The crystal structure described by Ba7Ga4Sb9 crystallizes in the orthorhombic Pmmn space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 10-coordinate geometry to two equivalent Ga(1), two equivalent Ga(2), two equivalent Sb(5), and four equivalent Sb(2) atoms. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to one Ga(2), one Sb(3), one Sb(4), one Sb(5), two equivalent Sb(1), and two equivalent Sb(2) atoms. In the third Ba site, Ba(3) is bonded in a 7-coordinate geometry to one Ga(2), two equivalent Sb(1), and four equivalent Sb(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 5-coordinate geometry to one Ba(1), one Sb(3), one Sb(4), and two equivalent Sb(2) atoms. In the second Ga site, Ga(2) is bonded in a distorted body-centered cubic geometry to one Ba(1), one Ba(3), two equivalent Ba(2), one Sb(1), one Sb(5), and two equivalent Sb(2) atoms. There are five inequivalent Sb sites. In the first Sb site, Sb(4) is bonded in a 7-coordinate geometry to four equivalent Ba(2), two equivalent Ga(1), and one Sb(3) atom. In the second Sb site, Sb(5) is bonded in a 8-coordinate geometry to two equivalent Ba(1), four equivalent Ba(2), and two equivalent Ga(2) atoms. In the third Sb site, Sb(1) is bonded in a 7-coordinate geometry to two equivalent Ba(3), four equivalent Ba(2), and one Ga(2) atom. In the fourth Sb site, Sb(2) is bonded to one Ba(1), two equivalent Ba(2), two equivalent Ba(3), one Ga(1), and one Ga(2) atom to form a mixture of distorted corner, face, and edge-sharing SbBa5Ga2 pentagonal bipyramids.
