The reaction of ruthenapentalyne with one equivalent of isocyanide led to the formation of a rare ruthenapentalene complex by nucleophilic addition. When excess isocyanides were used, the metal‐bridged ruthenaindene derivatives can be isolated and were formed by one carbon of isocyanide insertion into the ruthenacycle. Complexes 3 represent the first metallaindene derivatives with a second‐row transition metal at the bridge‐head position. The transformations from ruthenapentalyne via ruthenapentalene to ruthenaindene derivatives are of interest and can be extended to the syntheses of other polycyclic ruthenacycles. These unique metallacycles exhibit considerable stability and broad spectral absorption spanning the visible spectrum, enabling their potential applications in photoelectric materials.

金属桥连金属骨架的交替：从钌萘戊炔到钌戊戊烯和钌萘茚衍生物

Ruthenapentalyne与一当量的异氰化物的反应导致通过亲核加成反应形成稀有的Ruthenapentalene复合物。当使用过量的异氰酸酯时，可以分离出金属桥连的钌-茚满衍生物，并通过将一碳的异氰酸酯插入钌循环中来形成。配合物3代表在桥头位置带有第二行过渡金属的第一金属茂衍生物。从Ruthenapentalyne经由Ruthenapentalene到Ruthenaindene衍生物的转化是令人感兴趣的，并且可以扩展到其他多环Ruthenacycles的合成。这些独特的金属环化合物具有相当高的稳定性，并在可见光谱范围内具有较宽的光谱吸收率，从而使其在光电材料中具有潜在的应用前景。
