Intercalation compounds of layered niobates HA2Nb3O10 (A = Ca, Sr), which have perovskite-type oxide layers, with methylviologen dications have been synthesized. Although the two intercalation compounds were structurally similar, they exhibited different photochemical behavior. UV irradiation of the MV2+-intercalates caused electron transfer from the host to methylviologen dications in the HCa2Nb3O10 system, whereas photoreduction of Nb ions in the host lattice was observed in the HSr2Nb3O10 system.
