Ta Ta Ir Pd
Ta2IrPd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2IrPd cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 2-coordinate geometry to one Ta(2) and one Ir(1) atom. The Ta(1)-Ta(2) bond length is 1.66 Å. The Ta(1)-Ir(1) bond length is 2.40 Å. In the second Ta site, Ta(2) is bonded in a 2-coordinate geometry to one Ta(1) and one Pd(1) atom. The Ta(2)-Pd(1) bond length is 2.15 Å. Ir(1) is bonded in a 1-coordinate geometry to one Ta(1) atom. Pd(1) is bonded in a 1-coordinate geometry to one Ta(2) atom.
