Zn Os Os Pt
Os2PtZn crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) and one Zn(1) atom. The Os(1)-Os(2) bond length is 2.47 Å. The Os(1)-Zn(1) bond length is 0.37 Å. In the second Os site, Os(2) is bonded to one Os(1), six equivalent Os(2), and one Pt(1) atom to form distorted OsOs7Pt hexagonal bipyramids that share corners with six equivalent Os(2)Os7Pt hexagonal bipyramids, edges with six equivalent Pt(1)ZnOsPt6 hexagonal bipyramids, and edges with twelve equivalent Os(2)Os7Pt hexagonal bipyramids. All Os(2)-Os(2) bond lengths are 2.76 Å. The Os(2)-Pt(1) bond length is 3.27 Å. Pt(1) is bonded to one Os(2), six equivalent Pt(1), and one Zn(1) atom to form distorted PtZnOsPt6 hexagonal bipyramids that share corners with six equivalent Pt(1)ZnOsPt6 hexagonal bipyramids, edges with six equivalent Os(2)Os7Pt hexagonal bipyramids, and edges with twelve equivalent Pt(1)ZnOsPt6 hexagonal bipyramids. All Pt(1)-Pt(1) bond lengths are 2.76 Å. The Pt(1)-Zn(1) bond length is 2.90 Å. Zn(1) is bonded in a single-bond geometry to one Os(1) and one Pt(1) atom.
