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 Pd or a Pd cluster. A bis-acenaphthylene Pd chain cluster and an acenaphthylene-COT Pd sheet cluster were isolated, and the μ-π-coordination mode or the μ-oxidative π-addition mode of the acenaphthylene ligand in each cluster was elucidated by X-ray structure analysis.
由于多核簇与石墨碳材料负载的金属催化剂相关，其与稠合芳烃配体的配位行为一直备受关注。在此，我们报道苊烯与钯或钯簇的桥连配位行为。分离得到了一个双苊烯钯链簇和一个苊烯 - COT钯片簇，并通过X射线结构分析阐明了每个簇中苊烯配体的μ-π配位模式或μ-氧化π-加成模式。
