Mn Mn Os Pb
Mn2OsPb crystallizes in the monoclinic Cm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Os(1) and four equivalent Pb(1) atoms. The Mn(1)-Os(1) bond length is 0.41 Å. There are a spread of Mn(1)-Pb(1) bond distances ranging from 2.73-2.77 Å. In the second Mn site, Mn(2) is bonded in a distorted single-bond geometry to four equivalent Mn(2), four equivalent Os(1), and one Pb(1) atom. All Mn(2)-Mn(2) bond lengths are 2.99 Å. There are a spread of Mn(2)-Os(1) bond distances ranging from 3.35-3.38 Å. The Mn(2)-Pb(1) bond length is 2.96 Å. Os(1) is bonded in a single-bond geometry to one Mn(1) and four equivalent Mn(2) atoms. Pb(1) is bonded in a 5-coordinate geometry to one Mn(2) and four equivalent Mn(1) atoms.
