B B Os Pb
OsB2Pb crystallizes in the monoclinic Cm space group. Os(1) is bonded to four equivalent B(2) and one Pb(1) atom to form a mixture of corner and edge-sharing OsB4Pb square pyramids. There are a spread of Os(1)-B(2) bond distances ranging from 1.98-2.21 Å. The Os(1)-Pb(1) bond length is 1.84 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 5-coordinate geometry to one B(2) and four equivalent Pb(1) atoms. The B(1)-B(2) bond length is 2.41 Å. There are a spread of B(1)-Pb(1) bond distances ranging from 2.86-3.02 Å. In the second B site, B(2) is bonded in a distorted square co-planar geometry to four equivalent Os(1) and one B(1) atom. Pb(1) is bonded in a distorted single-bond geometry to one Os(1) and four equivalent B(1) atoms.
