Re B B Rh
ReRhB2 crystallizes in the triclinic P1 space group. Re(1) is bonded in a 12-coordinate geometry to four equivalent Rh(1), four equivalent B(1), and four equivalent B(2) atoms. There are a spread of Re(1)-Rh(1) bond distances ranging from 2.76-3.05 Å. There are a spread of Re(1)-B(1) bond distances ranging from 1.96-2.24 Å. There are a spread of Re(1)-B(2) bond distances ranging from 1.96-2.24 Å. Rh(1) is bonded to four equivalent Re(1), four equivalent Rh(1), two equivalent B(1), and two equivalent B(2) atoms to form a mixture of distorted corner and edge-sharing RhRe4B4Rh4 cuboctahedra. There are two shorter (2.90 Å) and two longer (2.96 Å) Rh(1)-Rh(1) bond lengths. There is one shorter (2.54 Å) and one longer (2.61 Å) Rh(1)-B(1) bond length. There is one shorter (2.68 Å) and one longer (2.75 Å) Rh(1)-B(2) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to four equivalent Re(1), two equivalent Rh(1), and one B(2) atom. The B(1)-B(2) bond length is 0.66 Å. In the second B site, B(2) is bonded in a single-bond geometry to four equivalent Re(1), two equivalent Rh(1), and one B(1) atom.
