In this HOT article, Díaz-Torres and Alvarez have developed a scale which attempts to quantify the weakly coordinating character of a variety of solvents and anions towards a transition metal or a lanthanide. This was made possible by analyzing crystal structures for the presence of coordinated and uncoordinated groups (solvents or anions) in the presence of a transition metal or a lanthanide and extracting from this coordinating ability indices. These indices should prove very useful in providing general trends allowing comparison between different solvents or anions and should be very useful for the broad organometallic community.
