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.
