Sm3Ag is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded in a 4-coordinate geometry to four equivalent Ag(1) atoms. Ag(1) is bonded to twelve equivalent Sm(1) atoms to form a mixture of face and corner-sharing AgSm12 cuboctahedra.
Sm3Ag is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded in a 4-coordinate geometry to four equivalent Ag(1) atoms. There are two shorter (3.33 Å) and two longer (3.51 Å) Sm(1)-Ag(1) bond lengths. Ag(1) is bonded to twelve equivalent Sm(1) atoms to form a mixture of face and corner-sharing AgSm12 cuboctahedra.
