The crystal structure described by GaAl3N4 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. Ga(1) is bonded to four equivalent N(1) atoms to form GaN4 tetrahedra that share corners with twelve equivalent Al(1)N4 tetrahedra. Al(1) is bonded to four equivalent N(1) atoms to form AlN4 tetrahedra that share corners with four equivalent Ga(1)N4 tetrahedra and corners with eight equivalent Al(1)N4 tetrahedra. N(1) is bonded to one Ga(1) and three equivalent Al(1) atoms to form corner-sharing NAl3Ga tetrahedra. is represented by the CIF card [CIF]
