Nanoscale octadecacobalta- and hexacosacobaltaclusters: Synthesis and spectroscopic fingerprinting

Strategies for the construction of TMS-protected first generation star and dendritic polyynes, which are subsequently metallated to give multiple Co2C2(CO)6 clusters, are reported. In the absence of crystallographic data, well-resolved 13C NMR spectroscopy is a powerful technique for confirming the presence of core, inner and peripheral cluster domains.

Graphical abstractStrategies for the construction of TMS-protected first generation star and dendritic polyynes, which can subsequently fully functionalized with Co2(CO)6-cluster units, are reported. 13C NMR spectroscopy is shown to be the most valuable tool in the characterization of the cobalt cluster-decorated products.Figure optionsDownload full-size imageDownload as PowerPoint slide
