Co B B Rh
RhCoB2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 11-coordinate geometry to two equivalent Rh(1), three equivalent Co(1), two equivalent B(1), and four equivalent B(2) atoms. Both Rh(1)-Rh(1) bond lengths are 2.62 Å. There are a spread of Rh(1)-Co(1) bond distances ranging from 2.37-3.21 Å. There is one shorter (2.11 Å) and one longer (2.27 Å) Rh(1)-B(1) bond length. There are a spread of Rh(1)-B(2) bond distances ranging from 2.25-2.62 Å. Co(1) is bonded in a single-bond geometry to three equivalent Rh(1), one B(1), and one B(2) atom. The Co(1)-B(1) bond length is 0.28 Å. The Co(1)-B(2) bond length is 0.84 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to two equivalent Rh(1), one Co(1), and one B(2) atom. The B(1)-B(2) bond length is 0.80 Å. In the second B site, B(2) is bonded in a 2-coordinate geometry to four equivalent Rh(1), one Co(1), and one B(1) atom.
