Room for one more? The structures of nanosized Pd52 and Pd66 clusters that are based upon a common Pd38 vertex‐truncated ν‐octahedral kernel have been determined. The 45 CO ligands in the Pd66 cluster (see core structure), [Pd66(CO)45(PEt3)16], are described in terms of one extra and 44 normal ligands, two of which undergo rearrangement to accommodate the 45th CO ligand without causing any substantial changes to the architecture of the metal core.
Einer geht noch: Die Strukturen eines Pd52‐ und eines Pd66‐Nanoclusters haben als Gemeinsamkeit eine abgestumpfte ν‐oktaedrische Pd38‐Anordnung. Einer der 45 CO‐Liganden von [Pd66(CO)45(PEt3)16] (Pd66‐Kern abgebildet) ist überzählig. Um Platz für diesen 45. CO‐Liganden zu schaffen, gehen zwei der 44 normalen Liganden eine Umlagerung ein, bei der die Anordnung der Metallzentren nicht grundlegend verändert wird.
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.
