Synthesis, structures and transformations of non-carbonyl chalcogenide-bridged clusters and polynuclear complexes of Groups 8–10 noble metals (Ru, Os, Rh, Ir, Pd, Pt) are considered. Various synthetic routes typically lead to trinuclear and tetranuclear clusters, while clusters of higher nuclearity are rare. Metal–metal bonding is important for the clusters of Groups 8 and 9 metals, while Pd and Pt form polynuclear chalcogenide-bridged complexes without M–M bonding. The chalcogenide-bridged clusters of these metals are excellent building blocks for constructing heterometallic clusters, including early–late transition metal heterobimetallic architectures.
