Tl Tl Fe Co
FeCoTl2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one FeCoTl2 cluster. Fe(1) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one Tl(1) atom. The Fe(1)-Co(1) bond length is 1.81 Å. The Fe(1)-Tl(1) bond length is 1.17 Å. Co(1) is bonded in a distorted single-bond geometry to one Fe(1) and one Tl(2) atom. The Co(1)-Tl(2) bond length is 0.36 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a single-bond geometry to one Fe(1) atom. In the second Tl site, Tl(2) is bonded in a single-bond geometry to one Co(1) atom.
