The material described by LaTe2 crystallizes in the monoclinic Pc space group. There are four inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to one Te(2), one Te(3), one Te(7), two equivalent Te(1), two equivalent Te(4), and two equivalent Te(6) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to one Te(1), one Te(2), one Te(6), one Te(7), one Te(8), two equivalent Te(3), and two equivalent Te(5) atoms. In the third La site, La(3) is bonded in a 9-coordinate geometry to one Te(1), one Te(2), one Te(4), one Te(7), one Te(8), two equivalent Te(3), and two equivalent Te(5) atoms. In the fourth La site, La(4) is bonded in a 9-coordinate geometry to one Te(2), one Te(5), one Te(7), two equivalent Te(4), two equivalent Te(6), and two equivalent Te(8) atoms. There are eight 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), two equivalent Te(2), and two equivalent Te(7) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to one La(1), one La(2), one La(3), one La(4), two equivalent Te(1), and two equivalent Te(8) atoms. In the third Te site, Te(3) is bonded to one La(1), two equivalent La(2), and two equivalent La(3) atoms to form a mixture of distorted edge and corner-sharing TeLa5 trigonal bipyramids. In the fourth Te site, Te(4) is bonded to one La(3), two equivalent La(1), and two equivalent La(4) atoms to form a mixture of distorted edge and corner-sharing TeLa5 trigonal bipyramids. In the fifth Te site, Te(5) is bonded to one La(4), two equivalent La(2), and two equivalent La(3) atoms to form a mixture of distorted edge and corner-sharing TeLa5 trigonal bipyramids. In the sixth Te site, Te(6) is bonded to one La(2), two equivalent La(1), and two equivalent La(4) atoms to form a mixture of distorted edge and corner-sharing TeLa5 trigonal bipyramids. In the seventh Te site, Te(7) is bonded in a 8-coordinate geometry to one La(1), one La(2), one La(3), one La(4), two equivalent Te(1), and two equivalent Te(8) atoms.
