Si3As4 crystallizes in the cubic P-43m space group. Si(1) is bonded to four equivalent As(1) atoms to form corner-sharing SiAs4 tetrahedra. As(1) is bonded in a trigonal non-coplanar geometry to three equivalent Si(1) atoms.
Si3As4 crystallizes in the cubic P-43m space group. Si(1) is bonded to four equivalent As(1) atoms to form corner-sharing SiAs4 tetrahedra. All Si(1)-As(1) bond lengths are 2.40 Å. As(1) is bonded in a trigonal non-coplanar geometry to three equivalent Si(1) atoms.
