OsSb3H is alpha Po structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three OsSb3H clusters. Os(1) is bonded in a 3-coordinate geometry to three equivalent Sb(1) atoms. All Os(1)-Sb(1) bond lengths are 1.66 Å. Sb(1) is bonded in a distorted L-shaped geometry to one Os(1) and one H(1) atom. The Sb(1)-H(1) bond length is 1.18 Å. H(1) is bonded in a distorted T-shaped geometry to three equivalent Sb(1) atoms.
