has recently attracted considerable attention. Complexes of anions with the electron
deficient s-tetrazine aromatic ring and other binding units (ie, urea and squaramide) have
been studied and compared using both high level MP2/6-311+ G** ab initio and molecular
interaction potential with and without polarization (MIPp and MIP, respectively) and
molecular electrostatic potential (MEP) calculations, in order to explore the physical nature …
