The crystal structure described by FeTe2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. Fe(1) is bonded to six equivalent Te(1) atoms to form a mixture of corner and edge-sharing FeTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. Te(1) is bonded in a 3-coordinate geometry to three equivalent Fe(1) atoms. is represented by the CIF file [CIF]
