The structure described by ZnSiAs2 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 Si(1)As4 tetrahedra. Si(1) is bonded to four equivalent As(1) atoms to form SiAs4 tetrahedra that share corners with four equivalent Si(1)As4 tetrahedra and corners with eight equivalent Zn(1)As4 tetrahedra. As(1) is bonded to two equivalent Zn(1) and two equivalent Si(1) atoms to form corner-sharing AsZn2Si2 tetrahedra. is represented by the CIF file [CIF]
