| Outline of Final Research Achievements |
Three types of multi-dimensional molecular network compounds, (i) a mixed-valence one-dimensional magnetic chain, (ii) an electron-donor/-acceptor alternating chain undergoing temperature-induced neutral-ionic phase transition, and (iii) a three-dimensional network compound undergoing quasi-Spin-Peierls transition, were investigated from the viewpoint of multiferroics that induces synergistic phenomena coupling magnetic spin ordering and electro-dipole ordering. We unfortunately could not find any data clearly indicate a multiferroic phenomenon, but succeeded in capturing a transition coupling between charge-ordering and structural phase transition by variations of dielectric signals.
