Conclusions

  1. 1.

    In a calorimetric study of the thermodynamics of the complexation of benzo-12-crown-4 with lithium, sodium, potassium, ammonium, and calcium thiocyanates, this ligand was found to have a tendency for partial filling of the coordination sphere of these cations.

  2. 2.

    The thermodynamic parameters are not in accord with the concept relating complex stability with the correspondence of the diameters of the metal cation and cavity of the crown ether.
