Cd Si Rh Rh
Rh2CdSi crystallizes in the monoclinic Cm space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), four equivalent Rh(2), and two equivalent Si(1) atoms. All Rh(1)-Rh(1) bond lengths are 3.21 Å. There are a spread of Rh(1)-Rh(2) bond distances ranging from 2.39-3.18 Å. There is one shorter (3.14 Å) and one longer (3.16 Å) Rh(1)-Si(1) bond length. In the second Rh site, Rh(2) is bonded in a single-bond geometry to four Rh(1,1) and one Cd(1) atom. Both Rh(2)-Rh(1) bond lengths are 2.81 Å. The Rh(2)-Cd(1) bond length is 0.55 Å. In the third Rh site, Rh(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), four equivalent Rh(2), and two equivalent Si(1) atoms. There is one shorter (3.14 Å) and one longer (3.16 Å) Rh(1)-Si(1) bond length. Cd(1) is bonded in a single-bond geometry to one Rh(2) and one Si(1) atom. The Cd(1)-Si(1) bond length is 2.06 Å. Si(1) is bonded in a 1-coordinate geometry to two equivalent Rh(1) and one Cd(1) atom.
