A unique metal addition to the edge of a triangular palladium sandwich cluster is reported. While the edge coordination sites of a parallel sandwich complex are narrow because of two sterically encumbering π-ligands, association of an additional metal atom to a metal sheet gives a wider coordination site. It was proved that the additional metal atom plays a crucial role in binding of cyclopentadienyl by a Pd3 sheet sandwich complex.

TLDR
Thiophene or selenophene is accommodated stably at a Pd 3 site supported by a backside μ3 -cyclooctatetraene ligand through the face-capping μ 3 -coordination and forms a unique spiro-type Pd 5 cluster.

Discrete Sandwich Compounds of Monolayer Palladium Sheets
TLDR
Despite the abundance of “sandwich” complexes, in which two cyclic aromatic hydrocarbon ligands flank a metal center, this motif has not been extended to sheets of multiple metal atoms, so two such compounds are prepared and isolated.

TLDR
The present results imply that the ligand design of theMetal clusters, especially for the backside ligand of the metal cluster site, is crucial to acquire a desired reactivity of metal clusters.
