BaUTe4 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 9-coordinate geometry to two equivalent Te(2), three equivalent Te(3), and four equivalent Te(1) atoms. U(1) is bonded in a 8-coordinate geometry to two equivalent Te(2), two equivalent Te(3), and four equivalent Te(1) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent U(1), and two equivalent Te(1) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to two equivalent Ba(1), two equivalent U(1), and one Te(2) atom. In the third Te site, Te(3) is bonded to three equivalent Ba(1) and two equivalent U(1) atoms to form a mixture of edge and corner-sharing TeBa3U2 trigonal bipyramids.
