Proton NMR study of Cr-Co heterometallic wheel complexes.
(1)H NMR spectra of the paramagnetic heterometallic complexes of general formula [cation][Cr(7)CoF(8)(O(2)C(t)Bu)(16)] have been recorded. The NMR spectra have allowed the investigation of the structure of these complexes in solution. These experiments show that the complexes are stable and maintain the solid state structure in solution, retaining the protonated amine in the cavity of the heterometallic ring.
