The compound described by Ti2Te3 crystallizes in the triclinic P-1 space group. There are four inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to one Te(3), one Te(5), two equivalent Te(1), and two equivalent Te(4) atoms to form a mixture of corner, face, and edge-sharing TiTe6 octahedra. The corner-sharing octahedral tilt angles range from 51-53°. In the second Ti site, Ti(2) is bonded to one Te(3), one Te(4), one Te(5), one Te(6), and two equivalent Te(2) atoms to form a mixture of distorted corner and edge-sharing TiTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-55°. In the third Ti site, Ti(3) is bonded to one Te(1), one Te(2), one Te(3), one Te(5), and two equivalent Te(6) atoms to form a mixture of distorted corner, face, and edge-sharing TiTe6 octahedra. The corner-sharing octahedral tilt angles range from 52-54°. In the fourth Ti site, Ti(4) is bonded to one Te(1), one Te(3), one Te(4), one Te(6), and two equivalent Te(5) atoms to form a mixture of corner, face, and edge-sharing TiTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-55°. There are six inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to one Ti(3), one Ti(4), and two equivalent Ti(1) atoms. In the second Te site, Te(2) is bonded in a distorted T-shaped geometry to one Ti(3) and two equivalent Ti(2) atoms. In the third Te site, Te(3) is bonded in a rectangular see-saw-like geometry to one Ti(1), one Ti(2), one Ti(3), and one Ti(4) atom. In the fourth Te site, Te(4) is bonded to one Ti(2), one Ti(4), and two equivalent Ti(1) atoms to form TeTi4 trigonal pyramids that share  a cornercorner with one Te(5)Ti5 trigonal bipyramid, corners with two equivalent Te(6)Ti4 trigonal pyramids, edges with two equivalent Te(5)Ti5 trigonal bipyramids, and  an edgeedge with one Te(4)Ti4 trigonal pyramid. In the fifth Te site, Te(5) is bonded to one Ti(1), one Ti(2), one Ti(3), and two equivalent Ti(4) atoms to form distorted TeTi5 trigonal bipyramids that share  a cornercorner with one Te(4)Ti4 trigonal pyramid,  a cornercorner with one Te(6)Ti4 trigonal pyramid,  an edgeedge with one Te(5)Ti5 trigonal bipyramid, edges with two equivalent Te(4)Ti4 trigonal pyramids, and edges with two equivalent Te(6)Ti4 trigonal pyramids. In the sixth Te site, Te(6) is bonded to one Ti(2), one Ti(4), and two equivalent Ti(3) atoms to form distorted TeTi4 trigonal pyramids that share  a cornercorner with one Te(5)Ti5 trigonal bipyramid, corners with two equivalent Te(4)Ti4 trigonal pyramids, edges with two equivalent Te(5)Ti5 trigonal bipyramids, and  an edgeedge with one Te(6)Ti4 trigonal pyramid. is represented by the CIF card [CIF]
