Tl Tc Ni
TcNiTl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcNiTl clusters. Tc(1) is bonded in a single-bond geometry to one Ni(1) atom. The Tc(1)-Ni(1) bond length is 0.84 Å. Ni(1) is bonded in a distorted linear geometry to one Tc(1) and one Tl(1) atom. The Ni(1)-Tl(1) bond length is 2.04 Å. Tl(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
