The material structure described by ULa2Te5 crystallizes in the monoclinic C2 space group. U(1) is bonded in a 8-coordinate geometry to one Te(1), one Te(4), one Te(5), one Te(6), two equivalent Te(2), and two equivalent Te(3) atoms. There are two inequivalent La sites.

In the fourth Te site, Te(4) is bonded in a 4-coordinate geometry to one U(1), one La(2), and two equivalent La(1) atoms. In the fifth Te site, Te(5) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent La(2), and two equivalent Te(6) atoms. In the sixth Te site, Te(6) is bonded in a 4-coordinate geometry to two equivalent U(1), two equivalent La(2), and two equivalent Te(5) atoms. is represented by the CIF file [CIF]
