Abstract The reaction between Os3(CO)12 and 2,6-naphthalenedicarboxylic acid (H2NDC) followed by reaction with tri-p-tolylphosphane produced the complex [Os2(CO)4(p-tolyl3P)2]4(μ4-NDCA)4 (1), which is the first example of a square octanuclear osmium complex. The reaction of Os3(CO)12 with benzene-1,3,5-tricarboxylic acid (H3BTC) yielded [Os2(CO)6]6(μ6-BTC)4 (2), which is the first octahedral dodecanuclear osmium complex. The basic metal building blocks in both 1 and 2 are Os2(CO)4L2 sawhorse units, which are linked together with di- or tricarboxylato spacers to form Os8 or Os12 supramolecules. The structures of these new MOF-like complexes were determined by X-ray crystallographic analysis.

钐锯木架配合物的方形和八面体超分子组装

摘要 Os3(CO)12 与 2,6-萘二甲酸 (H2NDC) 反应，然后与三对甲苯基膦反应生成复合物 [Os2(CO)4(p-tolyl3P)2]4(μ4-NDCA) 4 (1)，这是方形八核锇络合物的第一个例子。Os3(CO)12 与苯-1,3,5-三羧酸 (H3BTC) 反应生成 [Os2(CO)6]6(μ6-BTC)4 (2)，这是第一个八面体十二核锇络合物。1 和 2 中的基本金属构件是 Os2(CO)4L2 锯木架单元，它们与二或三羧基间隔物连接在一起形成 Os8 或 Os12 超分子。这些新的类似 MOF 的复合物的结构是通过 X 射线晶体学分析确定的。
