Tc Ir Ir Ru
TcRuIr2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcRuIr2 clusters. Tc(1) is bonded in an L-shaped geometry to one Ru(1) and two equivalent Ir(1) atoms. The Tc(1)-Ru(1) bond length is 0.63 Å. Both Tc(1)-Ir(1) bond lengths are 0.28 Å. Ru(1) is bonded in a 3-coordinate geometry to one Tc(1) and two equivalent Ir(1) atoms. Both Ru(1)-Ir(1) bond lengths are 0.61 Å. Ir(1) is bonded in a single-bond geometry to one Tc(1) and one Ru(1) atom.
