Summary:Nature utilises a variety of metal clusters as catalytic centers. Some of them make use of two or more metals in the catalytic site. The variation of metal‐metal distances plays an important role in several processes like charge transfer and weakening of bonds. X‐ray absorption spectroscopy can determine these metal‐metal distances in several states (crystal, solution or amorphous). However sometimes backscattering from light elements hides the metal‐metal contribution to the fine structure. Here we point out significance and accuracy of metal‐metal distances in a model system. Therefore a number of different refinement protocols are applied to the data. These protocols will be discussed focusing on the significance and accuracy of the metal‐metal distances extracted from the data.
