The material structure described by Ba(DyTe2)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 Dy sites. In the first Dy site, Dy(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 DyTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-59°. In the second Dy site, Dy(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 DyTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-59°. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ba(1), one Dy(2), and two equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing TeBa2Dy3 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Ba(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing TeBa2Dy3 square pyramids. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Dy(1), and two equivalent Dy(2) atoms. In the fourth Te site, Te(4) is bonded to two equivalent Ba(1) and three equivalent Dy(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Dy3 trigonal bipyramids. is represented by the CIF card [CIF]
