Materials Data on InGaSe2 by Materials Project
InGaSe2 crystallizes in the tetragonal P4/ncc space group. The structure is three-dimensional. In1+ is bonded in a square co-planar geometry to four equivalent Se2- atoms. All In–Se bond lengths are 3.18 Å. Ga3+ is bonded to four equivalent Se2- atoms to form edge-sharing GaSe4 tetrahedra. All Ga–Se bond lengths are 2.47 Å. Se2- is bonded in a 4-coordinate geometry to two equivalent In1+ and two equivalent Ga3+ atoms.
