Ag Ag Ir Pd
IrPdAg2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrPdAg2 clusters. Ir(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. Both Ir(1)-Ag(1) bond lengths are 0.40 Å. Pd(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. Both Pd(1)-Ag(1) bond lengths are 0.59 Å. Ag(1) is bonded in a single-bond geometry to one Ir(1), one Pd(1), and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 0.15 Å.
