Bond Valence Method

Bond Valence Method

The bond valence method (or bond valence sum) (not to be mistaken for the valence bond theory in quantum chemistry) is a popular method in coordination chemistry to estimate the oxidation states of atoms.

The basic idea is that the valence V of an atom is the sum of the individual bond valences vi surrounding the atom:

The individual bond valences in turn are calculated from the observed bond lengths.

Ri is the observed bond length, R0 is a tabulated parameter expressing the (ideal) bond length when the element i has exactly valence 1, and b is an empirical constant, typically 0.37 Å.

    I know no method to secure the repeal of bad or obnoxious laws so effective as their stringent execution.
    Ulysses S. Grant (1822–1885)

    Love cools, friendship falls off, brothers divide: in cities, mutinies; in countries, discord; in palaces, treason; and the bond cracked ‘twixt son and father.
