Bridging coordination of acenaphthylene to a Pd3 chain or a Pd4 sheet cluster

Abstract

The coordination behaviour of multinuclear clusters to fused arene ligands is of continuous interest due to its relevance to metal catalysts supported by graphitic carbon materials. Herein, we report the bridging coordination behaviour of acenaphthylene to a Pd₃ or a Pd₄ cluster. A bis-acenaphthylene Pd₃ chain cluster and an acenaphthylene-COT Pd₄ sheet cluster were isolated, and the μ₃-π-coordination mode or the μ₄-oxidative π-addition mode of the acenaphthylene ligand in each cluster was elucidated by X-ray structure analysis.
