Materials Data on Ga2FeSe4 by Materials Project
FeGa2Se4 crystallizes in the tetragonal P-42m space group. The structure is three-dimensional. Fe2+ is bonded to four equivalent Se2- atoms to form FeSe4 tetrahedra that share corners with eight equivalent GaSe4 tetrahedra. All Fe–Se bond lengths are 2.44 Å. Ga3+ is bonded to four equivalent Se2- atoms to form GaSe4 tetrahedra that share corners with four equivalent FeSe4 tetrahedra and corners with four equivalent GaSe4 tetrahedra. All Ga–Se bond lengths are 2.47 Å. Se2- is bonded in a trigonal non-coplanar geometry to one Fe2+ and two equivalent Ga3+ atoms.
