Os Pt Pt Br
OsPt2Br crystallizes in the triclinic P1 space group. Os(1) is bonded in a 2-coordinate geometry to four equivalent Pt(2) and two equivalent Br(1) atoms. There are a spread of Os(1)-Pt(2) bond distances ranging from 2.60-3.10 Å. There is one shorter (2.12 Å) and one longer (2.43 Å) Os(1)-Br(1) bond length. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to four equivalent Pt(2) and four equivalent Br(1) atoms. There are a spread of Pt(1)-Pt(2) bond distances ranging from 2.12-3.41 Å. There are a spread of Pt(1)-Br(1) bond distances ranging from 2.60-3.10 Å. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to four equivalent Os(1), two equivalent Pt(2), four equivalent Pt(1), and two equivalent Br(1) atoms. Both Pt(2)-Pt(2) bond lengths are 2.82 Å. There is one shorter (2.93 Å) and one longer (3.16 Å) Pt(2)-Br(1) bond length. Br(1) is bonded in a 1-coordinate geometry to two equivalent Os(1), two equivalent Pt(2), and four equivalent Pt(1) atoms.
