Zn Pt Rh Rh
Rh2PtZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Rh2PtZn clusters. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Rh(2) atom. The Rh(1)-Rh(2) bond length is 1.08 Å. In the second Rh site, Rh(2) is bonded in a 1-coordinate geometry to one Rh(1) and one Zn(1) atom. The Rh(2)-Zn(1) bond length is 2.18 Å. Pt(1) is bonded in a 1-coordinate geometry to one Zn(1) atom. The Pt(1)-Zn(1) bond length is 2.06 Å. Zn(1) is bonded in a 2-coordinate geometry to one Rh(2) and one Pt(1) atom.
