Ba(GdTe2)2 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. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to one Te(2), two equivalent Te(4), and three equivalent Te(3) atoms to form a mixture of corner and edge-sharing GdTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-60°. In the second Gd site, Gd(2) is bonded to one Te(4), two equivalent Te(2), and three equivalent Te(1) atoms to form a mixture of corner and edge-sharing GdTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-60°. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ba(1) and three equivalent Gd(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Gd3 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Ba(1), one Gd(1), and two equivalent Gd(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Gd3 trigonal bipyramids. In the third Te site, Te(3) is bonded to two equivalent Ba(1) and three equivalent Gd(1) atoms to form a mixture of corner and edge-sharing TeBa2Gd3 square pyramids. In the fourth Te site, Te(4) is bonded to two equivalent Ba(1), one Gd(2), and two equivalent Gd(1) atoms to form a mixture of distorted corner and edge-sharing TeBa2Gd3 trigonal bipyramids.
