Li Os Os W
LiWOs2 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a single-bond geometry to four equivalent W(1), one Os(2), and four equivalent Os(1) atoms. There are a spread of Li(1)-W(1) bond distances ranging from 3.08-3.38 Å. The Li(1)-Os(2) bond length is 0.70 Å. There are a spread of Li(1)-Os(1) bond distances ranging from 2.10-2.51 Å. W(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), four equivalent W(1), and two equivalent Os(1) atoms. All W(1)-W(1) bond lengths are 3.10 Å. There is one shorter (2.71 Å) and one longer (3.07 Å) W(1)-Os(1) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), two equivalent W(1), and four equivalent Os(2) atoms. There are a spread of Os(1)-Os(2) bond distances ranging from 1.97-2.41 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Li(1) and four equivalent Os(1) atoms.
