A prism carbon molecule C$_20$


Ohno, Koichi; Satoh, Hiroko; Iwamoto, Takeaki (2015). A prism carbon molecule C$_20$. Chemistry Letters, 44(5):712-714.

Abstract

A new carbon family with a prism structure has been found by quantum chemical calculations. The prism-$C_20$ has a $D_10h$ structure with double-layered decagonal rings connected each other by ten vertical CC bonds. The CC bond lengths are 0.144 nm on the decagonal rings and 0.148 nm on the side faces. The diameter of the ring is 0.465 nm. The $prism-C_20$ is expected to be stable, since the lowest energy barrier from it was estimated to be 158.0 kJ mol$^−1$.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
