Bond-valence parameters for solids
N. E. Brese,Michael O'Keeffe +1 more
TL;DR: In this article, it is shown that there is a strong linear correlation between the parameters for bonds from cations to pairs of anions, and this correlation is used to develop an interpolation scheme that allows the estimation of bond-valence parameters for 969 pairs of atoms.
