Be Os Os Rh
BeOs2Rh crystallizes in the triclinic P1 space group. Be(1) is bonded in a 1-coordinate geometry to two equivalent Os(1) and one Rh(1) atom. There is one shorter (1.12 Å) and one longer (1.77 Å) Be(1)-Os(1) bond length. The Be(1)-Rh(1) bond length is 2.37 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to two equivalent Be(1) and one Os(2) atom. The Os(1)-Os(2) bond length is 2.72 Å. In the second Os site, Os(2) is bonded in a 9-coordinate geometry to one Os(1), six equivalent Os(2), and two equivalent Rh(1) atoms. There are four shorter (2.67 Å) and two longer (2.73 Å) Os(2)-Os(2) bond lengths. There is one shorter (3.08 Å) and one longer (3.37 Å) Os(2)-Rh(1) bond length. Rh(1) is bonded in a single-bond geometry to one Be(1) and two equivalent Os(2) atoms.
