Ga2AsP is Chalcopyrite-like structured and crystallizes in the trigonal R3m space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one As(1) and three equivalent P(1) atoms to form GaAsP3 tetrahedra that share corners with six equivalent Ga(2)As3P tetrahedra and corners with six equivalent Ga(1)AsP3 tetrahedra. In the second Ga site, Ga(2) is bonded to three equivalent As(1) and one P(1) atom to form GaAs3P tetrahedra that share corners with six equivalent Ga(2)As3P tetrahedra and corners with six equivalent Ga(1)AsP3 tetrahedra. As(1) is bonded to one Ga(1) and three equivalent Ga(2) atoms to form AsGa4 tetrahedra that share corners with six equivalent As(1)Ga4 tetrahedra and corners with six equivalent P(1)Ga4 tetrahedra. P(1) is bonded to one Ga(2) and three equivalent Ga(1) atoms to form PGa4 tetrahedra that share corners with six equivalent As(1)Ga4 tetrahedra and corners with six equivalent P(1)Ga4 tetrahedra.
