观察到μ6-CO3(2-)阴离子的意外镶嵌支持了一个新的和不寻常的CO15团簇的形成。该排列被双酚配体进一步稳定，该双酚配体以类似于四高二氧杂杯[4]芳烃的方式组装。由于μ6-CO3(2-)阴离子在原位形成，反应以很低的产率进行，但通过添加碳酸盐进行定向合成提高了合成产率，并突出了该阴离子在整个组装过程中的关键作用。
Unexpected panelling by μ6-CO3(2-) anions has been observed to support the formation of a new and unusual Co15 cluster. The arrangement is further stabilised by bis-phenolate ligands which assemble in a manner akin to tetrahomodioxacalix[4]arene. The reaction proceeds in very low yield as μ6-CO3(2-) anions are formed in situ, but targeted synthesis by addition of carbonate improves synthetic yield and highlights the pivotal role of this anion in the overall assembly process.
