K2MnRh crystallizes in the monoclinic Cm space group. K(1) is bonded in a 2-coordinate geometry to one K(1), one Mn(1), and two equivalent Rh(1) atoms. The K(1)-K(1) bond length is 0.58 Å. The K(1)-Mn(1) bond length is 2.27 Å. There is one shorter (1.36 Å) and one longer (3.56 Å) K(1)-Rh(1) bond length. Mn(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Rh(1) atom. The Mn(1)-Rh(1) bond length is 2.64 Å. Rh(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Mn(1) atom.
