Ga4BiAs3 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. Ga(1) is bonded to one Bi(1) and three equivalent As(1) atoms to form corner-sharing GaBiAs3 tetrahedra. Bi(1) is bonded to four equivalent Ga(1) atoms to form BiGa4 tetrahedra that share corners with twelve equivalent As(1)Ga4 tetrahedra. As(1) is bonded to four equivalent Ga(1) atoms to form AsGa4 tetrahedra that share corners with four equivalent Bi(1)Ga4 tetrahedra and corners with eight equivalent As(1)Ga4 tetrahedra.
