FeCr2Te4 crystallizes in the monoclinic C2/m space group. Cr(1) is bonded in a 7-coordinate geometry to one Fe(1), three equivalent Te(1), and three equivalent Te(2) atoms. Fe(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), two equivalent Te(1), and four equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to three equivalent Cr(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge and corner-sharing TeCr3Fe2 square pyramids. In the second Te site, Te(1) is bonded in a rectangular see-saw-like geometry to three equivalent Cr(1) and one Fe(1) atom.
FeCr2Te4 crystallizes in the monoclinic C2/m space group. Cr(1) is bonded in a 7-coordinate geometry to one Fe(1), three equivalent Te(1), and three equivalent Te(2) atoms. The Cr(1)-Fe(1) bond length is 2.92 Å. There is one shorter (2.71 Å) and two longer (2.72 Å) Cr(1)-Te(1) bond lengths. There are two shorter (2.79 Å) and one longer (2.80 Å) Cr(1)-Te(2) bond length. Fe(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), two equivalent Te(1), and four equivalent Te(2) atoms. Both Fe(1)-Te(1) bond lengths are 2.73 Å. All Fe(1)-Te(2) bond lengths are 2.75 Å. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to three equivalent Cr(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge and corner-sharing TeCr3Fe2 square pyramids. In the second Te site, Te(1) is bonded in a rectangular see-saw-like geometry to three equivalent Cr(1) and one Fe(1) atom.
