Materials Data on Fe2Te3 by Materials Project
Fe2Te3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Fe3+ is bonded to six equivalent Te2- atoms to form a mixture of corner, edge, and face-sharing FeTe6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are three shorter (2.43 Å) and three longer (2.55 Å) Fe–Te bond lengths. Te2- is bonded in a 4-coordinate geometry to four equivalent Fe3+ atoms.
