SmFe10V2 crystallizes in the orthorhombic Immm space group. Sm(1) is bonded in a 20-coordinate geometry to two equivalent V(1), two equivalent Fe(4), four equivalent Fe(1), four equivalent Fe(2), and eight equivalent Fe(3) atoms. V(1) is bonded in a 14-coordinate geometry to one Sm(1), one V(1), two equivalent Fe(1), two equivalent Fe(2), four equivalent Fe(3), and four equivalent Fe(4) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 12-coordinate geometry to two equivalent Sm(1), two equivalent V(1), two equivalent Fe(2), two equivalent Fe(4), and four equivalent Fe(3) atoms. In the second Fe site, Fe(2) is bonded in a 12-coordinate geometry to two equivalent Sm(1), two equivalent V(1), two equivalent Fe(1), two equivalent Fe(4), and four equivalent Fe(3) atoms. In the third Fe site, Fe(3) is bonded to two equivalent Sm(1), two equivalent V(1), two equivalent Fe(1), two equivalent Fe(2), two equivalent Fe(3), and two equivalent Fe(4) atoms to form a mixture of distorted corner, face, and edge-sharing FeSm2V2Fe8 cuboctahedra.
