      abstract     = {This article complements an earlier topical review of the
                      chemical bond (Jones 2018 J. Phys.: Condens. Matter 30
                      153001), starting in the mid-19th century and seen from the
                      perspective of a condensed matter physicist. The discussion
                      of applications focused on the structure and properties of
                      phase change materials. We review here additional aspects of
                      chemistry, particularly some that have raised interest
                      recently in this context. Concepts such as 'electron-rich',
                      'electron-deficient (excess orbital)', 'hypervalent',
                      'three-centre', and 'metavalent' bonds, and 'multicentre
                      hyperbonding' are now found in the condensed matter
                      literature. They are surveyed here, as well as the bond in
                      metals and the 'Peierls' distortion. What are these
                      concepts, are they related, and are they sometimes new
                      labels for established, but unfamiliar ideas? 'Half bonds'
                      and 'fractional valencies' play a central role in this
                      discussion. It is remarkable that they were introduced 100
                      years ago, but ignored or forgotten, and have needed to be
                      rediscovered more than once.},
