Congeneric Array Database


Congeneric arrays are isoelectronic sets of chemical species with linear structure and reactivity behaviour traits. More than 100 congeneric series and planars have been collected together, along with some other interesting collections of chemical species that are not congeneric.

Pearson's Soft Lewis Acids

Pearson's features: Large species which are often neutral and easy to polarise, have low positive or delta+ charge and have electron pairs in their valence shells.
Klopman's features: Low energy LUMO but large magnitude LUMO coefficients. Form FMO controlled complexes with soft Lewis bases.
