Mn Ir Ir Rh
MnIr2Rh crystallizes in the monoclinic Cm space group. Mn(1) is bonded in a single-bond geometry to one Ir(1) and one Ir(2) atom. The Mn(1)-Ir(1) bond length is 0.73 Å. The Mn(1)-Ir(2) bond length is 2.94 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Mn(1) and one Rh(1) atom. The Ir(1)-Rh(1) bond length is 2.39 Å. In the second Ir site, Ir(2) is bonded to one Mn(1), six equivalent Ir(2), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing IrMnIr6Rh hexagonal bipyramids. All Ir(2)-Ir(2) bond lengths are 2.69 Å. The Ir(2)-Rh(1) bond length is 2.80 Å. Rh(1) is bonded in a 8-coordinate geometry to one Ir(1), one Ir(2), and six equivalent Rh(1) atoms. All Rh(1)-Rh(1) bond lengths are 2.69 Å.
