Ba2GaSbTe5 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. Ga(1) is bonded in a tetrahedral geometry to one Te(3), one Te(4), and two equivalent Te(1) atoms. Sb(1) is bonded in a 3-coordinate geometry to one Te(2) and four equivalent Te(1) atoms. There are four inequivalent Te sites. In the first Te site, Te(4) is bonded to four equivalent Ba(1) and one Ga(1) atom to form distorted TeBa4Ga square pyramids that share corners with four equivalent Te(2)Ba4Sb square pyramids, edges with two equivalent Te(4)Ba4Ga square pyramids, and edges with two equivalent Te(2)Ba4Sb square pyramids. In the second Te site, Te(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Ga(1), and two equivalent Sb(1) atoms. In the third Te site, Te(2) is bonded to four equivalent Ba(1) and one Sb(1) atom to form TeBa4Sb square pyramids that share corners with four equivalent Te(4)Ba4Ga square pyramids, corners with four equivalent Te(2)Ba4Sb square pyramids, and edges with two equivalent Te(4)Ba4Ga square pyramids. In the fourth Te site, Te(3) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one Ga(1) atom.
