Ba(TmTe2)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 Tm sites. In the first Tm site, Tm(1) is bonded to one Te(3), two equivalent Te(1), and three equivalent Te(2) atoms to form a mixture of corner and edge-sharing TmTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-58°. In the second Tm site, Tm(2) is bonded to one Te(1), two equivalent Te(3), and three equivalent Te(4) atoms to form a mixture of corner and edge-sharing TmTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-58°. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ba(1), one Tm(2), and two equivalent Tm(1) atoms to form a mixture of distorted corner and edge-sharing TeBa2Tm3 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Ba(1) and three equivalent Tm(1) atoms to form a mixture of corner and edge-sharing TeBa2Tm3 square pyramids. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Tm(1), and two equivalent Tm(2) atoms. In the fourth Te site, Te(4) is bonded to two equivalent Ba(1) and three equivalent Tm(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Tm3 trigonal bipyramids.
