What level of accuracy do we have? section[edit]
I am afraid that I do not understand this section--I am not familiar with the paper quoted --has any one any ideas? Axiosaurus (talk) 13:35, 10 January 2008 (UTC)
The section on what accuracy to expect is misleading as it is based on a single atom in a single rather complicated crystal structure detremination. According to the R-value quoted this structure determination is of limited quality. The proper conclusion would be that there is a problem with the determination of the atomic position of the corresponding Mo atom or (more probably) the neighbouring O(33). The reported bond length Mo(12)-O(33) is only 161pm, which is extremely unusual, i.e. most probably too short to be true, and this is excatly the information that can be read from the bond valence sum analysis.

Indeed this is a very misleading section. There are quite a few review articles which systematically investigate hundreds or thousands of molecules and extended solids with bond valence. In nearly all cases there is excellent agreement between experiment and BVS. BaconEggonomics (talk) 07:41, 11 December 2009 (UTC)
