Evolving patterns in boron cluster chemistry [PDF]

open access: yesPure and Applied Chemistry, 2003
Abstract This paper outlines the development of our knowledge and understanding of the structures and bonding of boron cluster compounds, with particular reference to the evolving complementary roles localized bonding and molecular orbital treatments have played in providing simple rationalizations of their polyhedral molecules.
