Specifically, the binding of hydrated salts of nickel and chromium by macrocyclic ligands has been reported by (iii) L. D. Prabhakar and C. Umarani, J.M.S.-Pure Appl.

21. The primary reason for not including any solvent in our simulations was the fact that the solvent-cation interactions would be minimal since the cation is itself insoluble in the solvents used (chloroform and THF). Also, since in our laboratory we have solubilized salts in bulk oligoethylene glycols, the modeling may be interpreted to reflect those observations.
