| Abstract: | PMR spectra were obtained from  bulk solvent molecules in anhydrous solutions of M(DMA)
6](ClO4)2 (M=Co, Ni) in N,N-dimethylacetamid (DMA). The free enthalpy of activation  G
c
* increases with increasing amount ofM
2+ as a result of the coordination of the cationsvia the oxygen atom resulting in a decrease of the
bond length. Cobalt(II) acts as a weaker electron pair acceptor than nickel(II). The oxygen coordination is also shown by the different line broadening of the C-methyl protons as compared to that of the N-methyl protons.Mit 6 Abbildungen |
