Sn Mo Os Os Os
MoOs3Sn is alpha Po structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three MoOs3Sn clusters. Mo(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. All Mo(1)-Os(1) bond lengths are 2.40 Å. Os(1) is bonded in a distorted single-bond geometry to one Mo(1) and one Sn(1) atom. The Os(1)-Sn(1) bond length is 1.70 Å. Sn(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms.
