Zn Zn Mo Rh
MoRhZn2 crystallizes in the monoclinic Cm space group. Mo(1) is bonded in a single-bond geometry to one Rh(1) and one Zn(2) atom. The Mo(1)-Rh(1) bond length is 1.66 Å. The Mo(1)-Zn(2) bond length is 3.33 Å. Rh(1) is bonded in a distorted single-bond geometry to one Mo(1) and one Zn(1) atom. The Rh(1)-Zn(1) bond length is 1.00 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one Rh(1) and one Zn(2) atom. The Zn(1)-Zn(2) bond length is 3.10 Å. In the second Zn site, Zn(2) is bonded to one Mo(1), one Zn(1), and six equivalent Zn(2) atoms to form a mixture of distorted edge and corner-sharing ZnZn7Mo hexagonal bipyramids. All Zn(2)-Zn(2) bond lengths are 2.78 Å.
