Cr Cr Sn Os
Cr2OsSn crystallizes in the monoclinic Pm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Cr(2) and one Sn(1) atom. The Cr(1)-Cr(2) bond length is 2.32 Å. The Cr(1)-Sn(1) bond length is 0.13 Å. In the second Cr site, Cr(2) is bonded to one Cr(1), four equivalent Cr(2), and one Os(1) atom to form a mixture of distorted corner and edge-sharing CrCr5Os octahedra. The corner-sharing octahedra are not tilted. All Cr(2)-Cr(2) bond lengths are 2.83 Å. The Cr(2)-Os(1) bond length is 2.51 Å. Os(1) is bonded in a distorted linear geometry to one Cr(2) and one Sn(1) atom. The Os(1)-Sn(1) bond length is 2.40 Å. Sn(1) is bonded in a single-bond geometry to one Cr(1) and one Os(1) atom.
