Hexasilabenzene (Si6H6). An ab initio theoretical study of its aromaticity and relative stability
Abstract
Ab initio calculations show that hexasilabenzene has approximately half the aromatic stabilization energy of benzene, and lies very close in stability to its valence Si6H6 isomers, this being in sharp contrast with the fact that benzene is by far the most stable C6H6 isomer.
