11. From a theoretical approach it was previously stated that in dinuclear dications connected by conjugated bridges the HOMO-LUMO gaps are very small. As a consequence, it was suggested that some of these species might have open-shell ground states.

17. The large temperature-independent paramagnetism contribution can also be due to the presence of traces of ferromagnetic impurities in the sample. In the cases of partially decomposed samples, ferromagnetic inorganic iron impurities were observed by Mössbauer spectrometry at very low temperature.
