迄今未知的双（4-吡啶基）硅烷2a、B与双（三乙基膦）铂和双（三乙基膦）钯双三氟甲磺酸酯5a、B b的自组装反应导致形成新的含硅菱形6a-d。此外，通过双吡啶缩醛4和双（三乙基膦）铂双三氟甲磺酸盐（5a）的反应制备了类似的碳类似物7。令人惊讶的是，双（4-吡啶基）酮（3）和铂络合物5a的反应由于酮的意外水合而得到类似的菱形10。求解硅配合物6a及其碳类似物7的晶体结构，并相互比较，以及与已知的含碳双核菱形进行比较。此外，对双核双卟啉配合物8进行了结构表征。电喷雾和FAB质谱数据也被报道，证实了形成的实体的双核性质。
Self-assembly reactions of hitherto unknown bis(4-pyridyl)silanes 2a,b with bis(triethylphosphine)platinum and bis(triethylphosphine)palladium bistriflates 5a,b lead to the formation of new silicon-containing rhomboids 6a−d. In addition, a similar carbon analogue 7 was prepared by reaction of bispyridyl acetal 4 and bis(triethylphosphine)platinum bistriflate (5a). Surprisingly, reaction of the bis(4-pyridyl)ketone (3) and the platinum complex 5a gave a similar rhomboid, 10, due to unexpected hydration of the ketone. The crystal structures of silicon complex 6a and its carbon analogue 7 were solved and compared to each other as well as to already known carbon-containing dinuclear rhomboids. In addition, the dinuclear bisporphyrin complex 8 was also characterized by X-ray structure analysis. Electrospray and FAB mass spectral data are reported as well, confirming the binuclear nature of the entities formed.
