4. These consideration on the magnetic interactions has been discussed on the basis of the room temperature structure, because no lowtemperature structural study was reported. We have analyzed lowtemperature structure of γ-phase at 25K and will report in the separature paper.

11. The asymmetric line shapes of AFMR signals remind us powder pattern. It is known that the FMR signals for the β-p-NPNN also have asymmetric line shapes. Thus, it may be common characteristic on the molecular spin system and may be associated with the non-localization of spins on isolated molecules.
