Outline of Final Research Achievements

A trigonal planar metalloligand is considered to nicely cover the polyhedral surface of a metal nanocluster core. Trialkynyl copper(I) complexes were selected as a triangular motif. The triangular motif was found to form a cage which accommodates a polyhydride-Ag cluster formulated as [Ag13H8]5+.
To explore a reactivity of a silver-alkynyl nanocluster, ligand exchange reactions between coordinating and free alkynyl ligands were examined. It was found that an electron rich alkynyl ligand was bound strongly because of not only a stronger sigma donation but also an effective pi donation.

Academic Significance and Societal Importance of the Research Achievements

金属ナノ粒子は、光センサーや発光などの光物性や高効率化学反応のための触媒として次世代を担う新物質群である。金属ナノ粒子の構造を知る手段として、配位子よって保護された金属ナノクラスターの構造解明は、極めて重要であり。そこで得られる構造的知見や、それに基づいた反応の理解は、金属ナノ粒子の化学の基盤的情報をなすものである。
