ON THE BO BOND-LENGTH IN OXADIBORIRANES

The moral of the story: when the experimental results do not agree with those of high-level ab initio calculations, experimentalists are encouraged to consider other possible interpretations. Based on precise calculations on oxadiboriranes 1 a-c, it became clear that for the X-ray structure analysis of 1 d a different refined model than the one originally published provides the ''correct'' structure.
