The crystal structure described by LaTe2 crystallizes in the orthorhombic Pma2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to one Te(3), two equivalent Te(1), two equivalent Te(2), and four equivalent Te(4) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to one Te(4), two equivalent Te(1), two equivalent Te(2), and four equivalent Te(3) atoms. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent Te(2) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent Te(1) atoms. In the third Te site, Te(3) is bonded to one La(1) and four equivalent La(2) 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. is represented by the CIF file [CIF]
