Ruthenium polypyridyl complexes with anticancer propertiesJuly 13th, 2007
The 2D NOESY spectrum shows a clear crosspeak between the 6A signal and that appearing at 7.22 ppm. Since it is known from the X-ray structure that 6A and 6T are close to each other in space, the signal al 7.22 ppm is assigned to the 6T atom. Once 6T is known, 5T, 4T and 3T can be assigned from the interactions shown in the COSY spectrum. Theoretically a NOESY peak should appear between 3T and 3T´, but this was not observed due to overlap. The set 6A´, 5A´, 4A´, 3A´ appears much more upfield than 6A, 5A, 4A, 3A and can be assigned analogously. In this case, 6A´ is also more deshielded than 3A´.
