The crystal structure described by Ba2GaBiTe5 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 to one Te(3), one Te(4), and two equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with three equivalent Bi(1)Te6 octahedra and  an edgeedge with one Bi(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 9-12°. Bi(1) is bonded to one Te(2), one Te(3), and four equivalent Te(1) atoms to form distorted BiTe6 octahedra that share corners with three equivalent Ga(1)Te4 tetrahedra, edges with two equivalent Bi(1)Te6 octahedra, and  an edgeedge with one Ga(1)Te4 tetrahedra. 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)Ba4Bi square pyramids, edges with two equivalent Te(2)Ba4Bi square pyramids, and edges with two equivalent Te(4)Ba4Ga 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 Bi(1) atoms. In the third Te site, Te(2) is bonded to four equivalent Ba(1) and one Bi(1) atom to form TeBa4Bi square pyramids that share corners with four equivalent Te(2)Ba4Bi square pyramids, corners with four equivalent Te(4)Ba4Ga square pyramids, and edges with two equivalent Te(4)Ba4Ga square pyramids. In the fourth Te site, Te(3) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Ga(1), and one Bi(1) atom. is represented by the CIF file [CIF]
