Os Os Os Os Pt Pt
Os2Pt crystallizes in the triclinic P1 space group. There are four inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to two equivalent Os(4) and one Pt(2) atom. There is one shorter (2.44 Å) and one longer (2.85 Å) Os(1)-Os(4) bond length. The Os(1)-Pt(2) bond length is 1.86 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to two equivalent Os(4), one Pt(1), and one Pt(2) atom. There is one shorter (2.18 Å) and one longer (2.85 Å) Os(2)-Os(4) bond length. The Os(2)-Pt(1) bond length is 1.32 Å. The Os(2)-Pt(2) bond length is 2.25 Å. In the third Os site, Os(3) is bonded in a water-like geometry to one Pt(1) and one Pt(2) atom. The Os(3)-Pt(1) bond length is 1.29 Å. The Os(3)-Pt(2) bond length is 1.28 Å. In the fourth Os site, Os(4) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Os(2), one Pt(1), and one Pt(2) atom. The Os(4)-Pt(1) bond length is 2.30 Å. The Os(4)-Pt(2) bond length is 2.36 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted linear geometry to one Os(2), one Os(3), and one Os(4) atom. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to one Os(1), one Os(2), one Os(3), and one Os(4) atom.
