ZnSnAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Zn(1) is bonded to four equivalent As(1) atoms to form ZnAs4 tetrahedra that share corners with four equivalent Zn(1)As4 tetrahedra and corners with eight equivalent Sn(1)As4 tetrahedra. Sn(1) is bonded to four equivalent As(1) atoms to form SnAs4 tetrahedra that share corners with four equivalent Sn(1)As4 tetrahedra and corners with eight equivalent Zn(1)As4 tetrahedra. As(1) is bonded to two equivalent Zn(1) and two equivalent Sn(1) atoms to form corner-sharing AsZn2Sn2 tetrahedra.
