Ni Os Os Rh
Os2RhNi crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to two equivalent Os(2) and two equivalent Ni(1) atoms. There is one shorter (2.79 Å) and one longer (3.12 Å) Os(1)-Os(2) bond length. There is one shorter (1.71 Å) and one longer (2.21 Å) Os(1)-Ni(1) bond length. In the second Os site, Os(2) is bonded in a 9-coordinate geometry to two equivalent Os(1), six equivalent Os(2), and one Rh(1) atom. There are four shorter (2.65 Å) and two longer (2.72 Å) Os(2)-Os(2) bond lengths. The Os(2)-Rh(1) bond length is 3.40 Å. Rh(1) is bonded in a 1-coordinate geometry to one Os(2) and two equivalent Ni(1) atoms. There is one shorter (2.00 Å) and one longer (2.44 Å) Rh(1)-Ni(1) bond length. Ni(1) is bonded in a 4-coordinate geometry to two equivalent Os(1) and two equivalent Rh(1) atoms.
