K K Rh Br
K2RhBr crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one Rh(1) and two equivalent Br(1) atoms. The K(1)-Rh(1) bond length is 1.57 Å. There is one shorter (2.93 Å) and one longer (3.35 Å) K(1)-Br(1) bond length. Rh(1) is bonded in a water-like geometry to two equivalent K(1) and two equivalent Br(1) atoms. There is one shorter (2.77 Å) and one longer (3.09 Å) Rh(1)-Br(1) bond length. Br(1) is bonded in a 6-coordinate geometry to four equivalent K(1) and two equivalent Rh(1) atoms.
