Magnetic Resonance Spectra

The proton magnetic resonance spectra of a series of octahedral bisethylene-diaminecobalt(III) complexes in the dipolar aprotic solvents NN-dimethylformamide, NN-dimethylacetamide, and dimethyl sulphoxide have been examined. Resonances due to the protons attached to the nitrogen atoms of the ethylenediamine ligands are easily observed in these solvents, and their chemical shifts are reported, together with some similar data determined in deuterium oxide, and 95% sulphuric acid. The pattern of the nitrogen proton resonances is dependent on the stereo- chemistry of the complex. Using these differences in resonance, the cis configuration of some recently synthesized solvent complexes has been confirmed. The observed resonances are assigned to the particular protons in most cases.

Partial molal volumes at 25� are reported for some 1 : 1 electrolytes, and for triphenylmethane, in dimethyl sulphoxide, N,N- dimethylformamide, acetonitrile, propylene carbonate, formamide and hexamethylphosphoramide. The assumption that ΔV�tr(Ph4As+) = ΔV�tr(BPh4-) was used to obtain ionic partial molal volumes of transfer from water to the non-aqueous solvents. Solvent compressibility appears to determine the partial molal volumes of non-electrolytes and large hydrophobic ions in solution. Values of ΔV�tr for cations and anions are discussed in terms of ion-solvent interactions, solvent-solvent interactions and steric crowding of large solvent molecules around the ions.

The liquid junction potentials (Ej) across aqueous saturated KCl/nonaqueous solvent junctions have been determined within the framework of the tetraphenylarsonium tetraphenylborate (tatb) extra- thermodynamic assumption. The nonaqueous solvents comprise methanol, ethylene glycol, acetonitrile, propylene carbonate, dimethylformamide and dimethyl sulfoxide. The Ej values obtained are fairly small (below 40 mV) in the case of protic solvents and fairly large (within 100-200 mV) in the case of dipolar aprotic solvents, as expected if primarily guided by solvent-solvent interactions across the liquid junctions. The results allow the aqueous saturated calomel electrode to be used to relate electrode potentials in different solvents.

Proton magnetic resonance shifts have been measured for the H2O–SO3 system. The results have been used to calculate the degree of ionization of water in solutions containing excess sulphuric acid. The shifts produced by a number of electrolytes in sulphuric acid have also been measured. The results are interpreted in terms of solute–solvent interactions, particularly polarization and hydrogen bonding, and are compared with the results of similar previous measurements on aqueous solutions.
