ReMn2Rh crystallizes in the monoclinic Pm space group. Re(1) is bonded in a single-bond geometry to one Mn(1) and one Rh(1) atom. The Re(1)-Mn(1) bond length is 2.88 Å. The Re(1)-Rh(1) bond length is 0.42 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one Re(1), one Mn(2), four equivalent Mn(1), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing MnMn5ReRh pentagonal bipyramids. The Mn(1)-Mn(2) bond length is 3.33 Å. All Mn(1)-Mn(1) bond lengths are 2.64 Å. The Mn(1)-Rh(1) bond length is 2.98 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Mn(1) and one Rh(1) atom. The Mn(2)-Rh(1) bond length is 1.02 Å. Rh(1) is bonded in a distorted water-like geometry to one Re(1), one Mn(1), and one Mn(2) atom.
