WebThe possibility of high and low spin complexes exists for configurations d 5-d 7 as well. The following general trends can be used to predict whether a complex will be high or low spin. For 3d metals (d 4-d 7): In general, low spin complexes occur with very strong ligands, such as cyanide. High spin complexes are common with ligands which are ...
