Tc Tc Mo Ir
MoTc2Ir crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MoTc2Ir cluster. Mo(1) is bonded in a distorted single-bond geometry to one Tc(2) atom. The Mo(1)-Tc(2) bond length is 1.77 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Tc(2) and one Ir(1) atom. The Tc(1)-Tc(2) bond length is 1.66 Å. The Tc(1)-Ir(1) bond length is 1.50 Å. In the second Tc site, Tc(2) is bonded in a 2-coordinate geometry to one Mo(1) and one Tc(1) atom. Ir(1) is bonded in a single-bond geometry to one Tc(1) atom.
