The compound described by FeTe3O8 crystallizes in the cubic Ia-3 space group. Fe(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. Te(1) is bonded in a distorted see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Fe(1) and one Te(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Te(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
