Tl Tl Cr Tc
CrTcTl2 crystallizes in the triclinic P1 space group. Cr(1) is bonded in a 6-coordinate geometry to two equivalent Cr(1), one Tc(1), one Tl(1), and two equivalent Tl(2) atoms. Both Cr(1)-Cr(1) bond lengths are 3.10 Å. The Cr(1)-Tc(1) bond length is 3.13 Å. The Cr(1)-Tl(1) bond length is 2.25 Å. There is one shorter (2.38 Å) and one longer (3.21 Å) Cr(1)-Tl(2) bond length. Tc(1) is bonded in a distorted single-bond geometry to one Cr(1) and one Tl(1) atom. The Tc(1)-Tl(1) bond length is 1.86 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted bent 150 degrees geometry to one Cr(1), one Tc(1), and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 0.42 Å. In the second Tl site, Tl(2) is bonded in a single-bond geometry to two equivalent Cr(1) and one Tl(1) atom.
