La Os Os W
LaWOs2 crystallizes in the monoclinic Cm space group. La(1) is bonded in a 6-coordinate geometry to two equivalent W(1) and four equivalent Os(1) atoms. There is one shorter (2.29 Å) and one longer (2.49 Å) La(1)-W(1) bond length. There are two shorter (2.20 Å) and two longer (2.96 Å) La(1)-Os(1) bond lengths. W(1) is bonded in a 3-coordinate geometry to two equivalent La(1) and two equivalent Os(1) atoms. Both W(1)-Os(1) bond lengths are 1.21 Å. Os(1) is bonded in a 1-coordinate geometry to two equivalent La(1) and one W(1) atom.
