LaTe2 crystallizes in the tetragonal P4bm space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to one Te(2), two equivalent Te(3), two equivalent Te(4), and four equivalent Te(1) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to one Te(4), four equivalent Te(1), and four equivalent Te(2) atoms. In the third La site, La(3) is bonded in a 9-coordinate geometry to one Te(3), four equivalent Te(1), and four equivalent Te(2) atoms. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to one La(2), one La(3), two equivalent La(1), and four equivalent Te(1) atoms. In the second Te site, Te(2) is bonded to one La(1), two equivalent La(2), and two equivalent La(3) atoms to form a mixture of distorted corner and edge-sharing TeLa5 trigonal bipyramids. In the third Te site, Te(3) is bonded to one La(3) and four equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing TeLa5 trigonal bipyramids. In the fourth Te site, Te(4) is bonded to one La(2) and four equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing TeLa5 trigonal bipyramids.
