FeAg2Sn is beta Plutonium-derived structured and crystallizes in the triclinic P1 space group. Fe(1) is bonded in a 10-coordinate geometry to two equivalent Fe(1), two equivalent Ag(1), four equivalent Ag(2), and four equivalent Sn(1) atoms. Both Fe(1)-Fe(1) bond lengths are 3.00 Å. There is one shorter (2.61 Å) and one longer (2.77 Å) Fe(1)-Ag(1) bond length. There are a spread of Fe(1)-Ag(2) bond distances ranging from 2.98-3.43 Å. There are a spread of Fe(1)-Sn(1) bond distances ranging from 2.48-3.18 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to two equivalent Fe(1), two equivalent Ag(1), four equivalent Ag(2), and two equivalent Sn(1) atoms. Both Ag(1)-Ag(1) bond lengths are 3.00 Å. There are a spread of Ag(1)-Ag(2) bond distances ranging from 2.54-3.32 Å. There is one shorter (2.80 Å) and one longer (2.95 Å) Ag(1)-Sn(1) bond length. In the second Ag site, Ag(2) is bonded in a 12-coordinate geometry to four equivalent Fe(1), two equivalent Ag(2), four equivalent Ag(1), and two equivalent Sn(1) atoms. Both Ag(2)-Ag(2) bond lengths are 3.00 Å. There is one shorter (2.80 Å) and one longer (2.95 Å) Ag(2)-Sn(1) bond length. Sn(1) is bonded in a 10-coordinate geometry to four equivalent Fe(1), two equivalent Ag(1), two equivalent Ag(2), and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 3.00 Å.
