Y Os Os Br
YOs2Br crystallizes in the triclinic P1 space group. Y(1) is bonded in a 4-coordinate geometry to two equivalent Os(1) and two equivalent Os(2) atoms. There is one shorter (3.08 Å) and one longer (3.32 Å) Y(1)-Os(1) bond length. There is one shorter (3.08 Å) and one longer (3.32 Å) Y(1)-Os(2) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 10-coordinate geometry to two equivalent Y(1), six equivalent Os(1), and two equivalent Br(1) atoms. There are four shorter (3.00 Å) and two longer (3.17 Å) Os(1)-Os(1) bond lengths. There is one shorter (3.01 Å) and one longer (3.26 Å) Os(1)-Br(1) bond length. In the second Os site, Os(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Y(1) and two equivalent Br(1) atoms. There is one shorter (1.50 Å) and one longer (1.94 Å) Os(2)-Br(1) bond length. Br(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Os(1) and two equivalent Os(2) atoms.
