Since it is absolutely necessary to correct the bond lengths for systematic errors by individual fitting of do (see Sect. 2), it is indispensable to use a common B for the different oxidation states of M. This requirement appears to be fulfilled at least for vIV'V-o compounds, see above and Refs. 15-17. 1 The Quality of the Structure Determinations of the (Poly)oxometalates In view of the difficulties with the derivation of the bond length-bond valence parameters B and do because of inaccurate bond lengths stated in the literature for the structures, we give in the following a relevant characterization of the published structural data.
