SrMnOs2 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrMnOs2 cluster. Sr(1) is bonded in a single-bond geometry to one Mn(1) atom. The Sr(1)-Mn(1) bond length is 1.87 Å. Mn(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Os(2) atom. The Mn(1)-Os(2) bond length is 1.96 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) atom. The Os(1)-Os(2) bond length is 0.98 Å. In the second Os site, Os(2) is bonded in a 2-coordinate geometry to one Mn(1) and one Os(1) atom.
