K Re Rh Rh
KReRh2 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Rh(1) atoms. There are a spread of K(1)-Rh(1) bond distances ranging from 2.53-3.14 Å. Re(1) is bonded in a 6-coordinate geometry to eight equivalent Rh(1) atoms. There are a spread of Re(1)-Rh(1) bond distances ranging from 2.53-3.14 Å. Rh(1) is bonded in a 10-coordinate geometry to four equivalent K(1), four equivalent Re(1), and two equivalent Rh(1) atoms. Both Rh(1)-Rh(1) bond lengths are 2.77 Å.
