Herein, we report the synthesis and atomic structure of the cluster‐assembled [Au 60 Se 2 (Ph 3 P) 10 (SeR) 15 ] + material. Five icosahedral Au 13 building blocks from a closed gold ring with Au–Se–Au linkages. Interestingly, two Se atoms (without the phenyl tail) locate in the center of the cluster, stabilized by the Se‐(Au) 5 interactions. The ring‐like nanocluster is unprecedented in previous experimental and theoretical studies of gold nanocluster structures. In addition, our optical and electrochemical studies show that the electronic properties of the icosahedral Au 13 units still remain unchanged in the penta‐twinned Au 60 nanocluster, and this new material might be a promising in optical limiting material. This work offers a basis for deep understanding on controlling the cluster‐assembled materials for tailoring their functionalities.
