SrOs3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two SrOs3 clusters. Sr(1) is bonded in a distorted trigonal planar geometry to one Os(1), one Os(2), and one Os(3) atom. The Sr(1)-Os(1) bond length is 1.02 Å. The Sr(1)-Os(2) bond length is 1.63 Å. The Sr(1)-Os(3) bond length is 1.41 Å. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Sr(1) atom. In the third Os site, Os(3) is bonded in a single-bond geometry to one Sr(1) atom.
