Zr Zr Tc Rh
Zr2TcRh crystallizes in the monoclinic Cm space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 4-coordinate geometry to one Zr(2) and three equivalent Rh(1) atoms. The Zr(1)-Zr(2) bond length is 2.21 Å. There is one shorter (2.70 Å) and two longer (3.27 Å) Zr(1)-Rh(1) bond lengths. In the second Zr site, Zr(2) is bonded in a distorted single-bond geometry to one Zr(1) and one Tc(1) atom. The Zr(2)-Tc(1) bond length is 1.67 Å. Tc(1) is bonded in a 2-coordinate geometry to one Zr(2) and one Rh(1) atom. The Tc(1)-Rh(1) bond length is 1.75 Å. Rh(1) is bonded in a 2-coordinate geometry to three equivalent Zr(1) and one Tc(1) atom.
