Co Os Os Pb
Os2CoPb crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 8-coordinate geometry to four equivalent Co(1) and four equivalent Pb(1) atoms. There are a spread of Os(1)-Co(1) bond distances ranging from 3.21-3.26 Å. There are a spread of Os(1)-Pb(1) bond distances ranging from 2.59-2.64 Å. In the second Os site, Os(2) is bonded in a body-centered cubic geometry to four equivalent Co(1) and four equivalent Pb(1) atoms. There are a spread of Os(2)-Co(1) bond distances ranging from 2.67-2.72 Å. There are a spread of Os(2)-Pb(1) bond distances ranging from 2.59-2.64 Å. Co(1) is bonded in a 13-coordinate geometry to four equivalent Os(1), four equivalent Os(2), four equivalent Co(1), and one Pb(1) atom. All Co(1)-Co(1) bond lengths are 3.02 Å. The Co(1)-Pb(1) bond length is 3.16 Å. Pb(1) is bonded in a distorted body-centered cubic geometry to four equivalent Os(1), four equivalent Os(2), and one Co(1) atom.
