Basicity of water in organic solvents (nitromethane, propane-1,2-diyl carbonate and acetone) using the 1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecanenickel(II) cation as a probe of electron-pair acceptance
The basicity of water in nitromethane (NM), propane-1,2-diylcarbonate (PDC) and acetone (AC) has been examined using spectral data for (1R,4S,8R,11S)-1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecane-nickel(II)[Ni(TMC)]2+}. In these solventswater monomers are in equilibrium with their dimers: the water monomers are only weakly coordinated to the chelate in these solvents, whereas the dimers
