Y Zn Tc Tc
YTc2Zn crystallizes in the monoclinic Cm space group. Y(1) is bonded to six equivalent Y(1), one Tc(1), and one Zn(1) atom to form a mixture of corner and edge-sharing YY6ZnTc hexagonal bipyramids. All Y(1)-Y(1) bond lengths are 2.98 Å. The Y(1)-Tc(1) bond length is 3.59 Å. The Y(1)-Zn(1) bond length is 3.48 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 8-coordinate geometry to one Y(1), one Tc(2), and six equivalent Tc(1) atoms. The Tc(1)-Tc(2) bond length is 2.06 Å. All Tc(1)-Tc(1) bond lengths are 2.98 Å. In the second Tc site, Tc(2) is bonded in a single-bond geometry to one Tc(1) and one Zn(1) atom. The Tc(2)-Zn(1) bond length is 0.11 Å. Zn(1) is bonded in a single-bond geometry to one Y(1) and one Tc(2) atom.
