Fe Fe Os Pb
OsFe2Pb crystallizes in the triclinic P1 space group. Os(1) is bonded in a 1-coordinate geometry to two equivalent Fe(1) and one Pb(1) atom. There is one shorter (2.26 Å) and one longer (2.46 Å) Os(1)-Fe(1) bond length. The Os(1)-Pb(1) bond length is 0.98 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Fe(2), and two equivalent Pb(1) atoms. There is one shorter (1.77 Å) and one longer (2.79 Å) Fe(1)-Fe(2) bond length. There is one shorter (2.60 Å) and one longer (2.77 Å) Fe(1)-Pb(1) bond length. In the second Fe site, Fe(2) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and two equivalent Pb(1) atoms. There is one shorter (2.26 Å) and one longer (2.46 Å) Fe(2)-Pb(1) bond length. Pb(1) is bonded in a 1-coordinate geometry to one Os(1), two equivalent Fe(1), and two equivalent Fe(2) atoms.
