The structure described by FeGa2Se4 crystallizes in the tetragonal P-42m space group. Fe(1) is bonded to four equivalent Se(1) atoms to form FeSe4 tetrahedra that share corners with eight equivalent Ga(1)Se4 tetrahedra. Ga(1) is bonded to four equivalent Se(1) atoms to form GaSe4 tetrahedra that share corners with four equivalent Fe(1)Se4 tetrahedra and corners with four equivalent Ga(1)Se4 tetrahedra. Se(1) is bonded in a trigonal non-coplanar geometry to one Fe(1) and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
