| Outline of Final Research Achievements |
In this project, we focused on the contiguous π-coordination bonds which are formed at the molecular interface between the pπ-conjugated unsaturated hydrocarbons and the metal assemblies. We developed a synthetic method to construct the extended contiguous π-coordination bonds, that enabled construction of one-dimensional metal chain sandwich compounds having ten metal atoms. We also studied the two-dimensional contiguous multiple π-coordination bonds. Several aromatic ligands were successfully introduced on a trinuclear cluster face, and the ligand substitution mechanism was elucidated. Furthermore, we elucidated the bonding nature of the contiguous π-coordination bonds through experimental and theoretical analyses.
