Pd Ru Ru Rh
Ru2RhPd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ru2RhPd clusters. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Pd(1) atom. The Ru(1)-Rh(1) bond length is 1.92 Å. The Ru(1)-Pd(1) bond length is 1.51 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Rh(1) atom. The Ru(2)-Rh(1) bond length is 0.19 Å. Rh(1) is bonded in a single-bond geometry to one Ru(1), one Ru(2), and one Pd(1) atom. The Rh(1)-Pd(1) bond length is 1.42 Å. Pd(1) is bonded in a 2-coordinate geometry to one Ru(1) and one Rh(1) atom.
