InGaAs2 is Chalcopyrite-like structured and crystallizes in the tetragonal P-4m2 space group. In(1) is bonded to four equivalent As(1) atoms to form InAs4 tetrahedra that share corners with four equivalent In(1)As4 tetrahedra and corners with eight equivalent Ga(1)As4 tetrahedra. Ga(1) is bonded to four equivalent As(1) atoms to form GaAs4 tetrahedra that share corners with four equivalent Ga(1)As4 tetrahedra and corners with eight equivalent In(1)As4 tetrahedra. As(1) is bonded to two equivalent In(1) and two equivalent Ga(1) atoms to form corner-sharing AsIn2Ga2 tetrahedra.
