K Mo Os Os
KMoOs2 crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to one Mo(1), one Os(1), and two equivalent Os(2) atoms. The K(1)-Mo(1) bond length is 0.55 Å. The K(1)-Os(1) bond length is 2.41 Å. There is one shorter (3.12 Å) and one longer (3.55 Å) K(1)-Os(2) bond length. Mo(1) is bonded in a single-bond geometry to one K(1) and two equivalent Os(2) atoms. There is one shorter (2.41 Å) and one longer (2.96 Å) Mo(1)-Os(2) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to one K(1) and two equivalent Os(2) atoms. There is one shorter (2.33 Å) and one longer (3.08 Å) Os(1)-Os(2) bond length. In the second Os site, Os(2) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent Mo(1), two equivalent Os(1), and two equivalent Os(2) atoms. Both Os(2)-Os(2) bond lengths are 2.55 Å.
