The material described by UDyTe4 crystallizes in the monoclinic Cm space group. U(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. Dy(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 four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent U(1) and two equivalent Dy(1) atoms to form a mixture of corner and edge-sharing TeDy2U2 trigonal pyramids. In the second Te site, Te(2) is bonded to two equivalent U(1) and two equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing TeDy2U2 trigonal pyramids. In the third Te site, Te(3) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent Dy(1), and two equivalent Te(4) atoms. In the fourth Te site, Te(4) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent Dy(1), and two equivalent Te(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
