Materials Data on GeSe2 by Materials Project
GeSe2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Ge4+ is bonded to four equivalent Se2- atoms to form corner-sharing GeSe4 tetrahedra. All Ge–Se bond lengths are 2.40 Å. Se2- is bonded in a water-like geometry to two equivalent Ge4+ atoms.
