The compound described by Cr(FeTe2)2 crystallizes in the triclinic P-1 space group. Cr(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form CrTe6 octahedra that share corners with six equivalent Fe(2)Te6 octahedra, edges with two equivalent Cr(1)Te6 octahedra, edges with two equivalent Fe(2)Te6 octahedra, and edges with four equivalent Fe(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 6-8°. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form FeTe6 octahedra that share edges with two equivalent Fe(1)Te6 octahedra, edges with four equivalent Cr(1)Te6 octahedra, and edges with four equivalent Fe(2)Te6 octahedra. In the second Fe site, Fe(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form FeTe6 octahedra that share corners with six equivalent Cr(1)Te6 octahedra, edges with two equivalent Cr(1)Te6 octahedra, edges with two equivalent Fe(2)Te6 octahedra, and edges with four equivalent Fe(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 6-8°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to one Cr(1), one Fe(2), and two equivalent Fe(1) atoms. In the second Te site, Te(2) is bonded to two equivalent Cr(1), one Fe(1), and two equivalent Fe(2) atoms to form a mixture of corner and edge-sharing TeCr2Fe3 square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
