Phosphorus- and arsenic-containing cobalt clusters are an interesting class of compounds that continue to provide new structures with captivating bonding patterns. Although the first members of this family were reported 45 years ago, the number of such species is still limited within the broad family of transition metal complexes bearing pnictogen atoms. Herein, we present the reaction of Co(CO) as a cobalt source with a number of phosphorus- and arsenic-containing compounds under variable reaction conditions. These reactions result in various known and novel cobalt phosphorus and cobalt arsenic clusters in which different nuclearity ratios between P/As and Co exist. All those clusters were characterized by X-ray structural analysis and partly by IR, P{H} NMR, EI-MS and elemental analysis. This comprehensive study is the first detailed study in this field that reveals the richness of compounds that could be obtained only by modifying the ratio of used reactants and the involved reaction conditions.
含磷和砷的钴簇合物是一类有趣的化合物,它们不断提供具有迷人键合模式的新结构。尽管该家族的首批成员是在45年前报道的,但在含有氮族元素原子的过渡金属配合物这一广泛家族中,此类物种的数量仍然有限。在此,我们展示了以Co(CO)作为钴源,在可变反应条件下与多种含磷和砷的化合物发生的反应。这些反应产生了各种已知和新型的钴磷和钴砷簇合物,其中P/As与Co之间存在不同的核数比。所有这些簇合物均通过X射线结构分析进行表征,部分还通过红外光谱、磷的核磁共振谱、电子轰击质谱和元素分析进行表征。这项全面的研究是该领域的首次详细研究,揭示了仅通过改变所用反应物的比例和相关反应条件就能获得的化合物的丰富性。
