Mg Rh Rh W
MgWRh2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 4-coordinate geometry to one W(1), one Rh(2), and four equivalent Rh(1) atoms. The Mg(1)-W(1) bond length is 2.71 Å. The Mg(1)-Rh(2) bond length is 3.45 Å. There are a spread of Mg(1)-Rh(1) bond distances ranging from 2.12-2.52 Å. W(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent Rh(1), and four equivalent Rh(2) atoms. There are a spread of W(1)-Rh(1) bond distances ranging from 2.43-2.78 Å. There are a spread of W(1)-Rh(2) bond distances ranging from 2.43-2.78 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) and four equivalent W(1) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent W(1), and four equivalent Rh(2) atoms. All Rh(2)-Rh(2) bond lengths are 2.89 Å.
