Tc Pd Pd Rh
TcRhPd2 crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a single-bond geometry to one Rh(1) and one Pd(1) atom. The Tc(1)-Rh(1) bond length is 0.50 Å. The Tc(1)-Pd(1) bond length is 3.28 Å. Rh(1) is bonded in a single-bond geometry to one Tc(1) and one Pd(2) atom. The Rh(1)-Pd(2) bond length is 2.71 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to one Tc(1), one Pd(2), and six equivalent Pd(1) atoms to form PdTcPd7 hexagonal bipyramids that share corners with six equivalent Pd(1)TcPd7 hexagonal bipyramids, edges with six equivalent Pd(2)Pd7Rh hexagonal bipyramids, and edges with twelve equivalent Pd(1)TcPd7 hexagonal bipyramids. The Pd(1)-Pd(2) bond length is 2.69 Å. All Pd(1)-Pd(1) bond lengths are 2.76 Å. In the second Pd site, Pd(2) is bonded to one Rh(1), one Pd(1), and six equivalent Pd(2) atoms to form distorted PdPd7Rh hexagonal bipyramids that share corners with six equivalent Pd(2)Pd7Rh hexagonal bipyramids, edges with six equivalent Pd(1)TcPd7 hexagonal bipyramids, and edges with twelve equivalent Pd(2)Pd7Rh hexagonal bipyramids. All Pd(2)-Pd(2) bond lengths are 2.76 Å.
