Abstract
Equations relating bond strength (valence) to bond length have been developed for tungsten-oxygen and phosphorus-oxygen bonds. Bond-valence sums have been carried out for the different tungsten atoms in phosphate tungsten bronzes and other mixed-valence tungsten oxides and for the Mo atoms in TeMo 5O 16. Valences intermediate between 5 and 6 are generally found, in agreement with physical measurements that indicate delocalization of d electrons in these materials. Evidence is presented that shows that the degree of distortion of WO 6 octahedra increases with apparent oxidation state of tungsten.
