Materials Data on Al3GaN4 by Materials Project
GaAl3N4 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. The structure is three-dimensional. Ga3+ is bonded to four equivalent N3- atoms to form GaN4 tetrahedra that share corners with twelve equivalent AlN4 tetrahedra. All Ga–N bond lengths are 1.96 Å. Al3+ is bonded to four equivalent N3- atoms to form AlN4 tetrahedra that share corners with four equivalent GaN4 tetrahedra and corners with eight equivalent AlN4 tetrahedra. All Al–N bond lengths are 1.90 Å. N3- is bonded to one Ga3+ and three equivalent Al3+ atoms to form corner-sharing NAl3Ga tetrahedra.
