The material structure described by YFe2O4 crystallizes in the tetragonal I4_1/a space group. Y(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Fe(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent Y(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge and corner-sharing OY2Fe2 tetrahedra. is represented by the CIF card [CIF]
