Zr Tl Cd Cd
ZrCd2Tl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrCd2Tl clusters. Zr(1) is bonded in a distorted linear geometry to one Cd(1) and one Tl(1) atom. The Zr(1)-Cd(1) bond length is 3.17 Å. The Zr(1)-Tl(1) bond length is 2.66 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 2-coordinate geometry to one Zr(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 1.49 Å. In the second Cd site, Cd(2) is bonded in a distorted single-bond geometry to one Cd(1) atom. Tl(1) is bonded in a distorted single-bond geometry to one Zr(1) atom.
