Nach vielen vergeblichen Bemühungen über zwei Jahrzehnte gelang nun die erste Kristallstrukturanalyse eines [Co2(CO)6]‐komplexierten Propargylkations, des BF4‐Salzes von 1. Das kationische Zentrum ist zwar nahezu ideal sp2‐hybridisiert, die Metallcluster weisen aber dennoch erheblich unterschiedliche Strukturen auf.
After two decades of thwarted efforts, the first X‐ray structure analysis of a [Co2(CO)6]‐complexed propagyl cation, the BF4 salt of 1, has been reported. The carbocationic center is almost ideally sp2‐hydbridized, while the metal clusters exhibit substantial structural inequivalency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
