Materials Data on Sn3As4 by Materials Project

Sn3As4 crystallizes in the cubic P-43m space group. The structure is three-dimensional. Sn4+ is bonded to four equivalent As3- atoms to form corner-sharing SnAs4 tetrahedra. All Sn–As bond lengths are 2.69 Å. As3- is bonded in a trigonal non-coplanar geometry to three equivalent Sn4+ atoms.
