چکیده

We synthesized and characterized bromide-bridged Pd(III) chain complexes, [Pd(en)2Br](MalCn-Y)2·H2O (en = ethylenediamine; MalCn-Y = dialkyl sulfomalonate; n: the number of carbon atoms) (n = 7 and 12). The compound with n = 7 showed charge-bistability near room temperature. In addition, it is shown that the Pd(III) state is maintained in the thin film state.

Cation-dependent magnetic ordering and room-temperature bistability in azido-bridged perovskite-type compounds.

A series of end-to-end azido-bridged perovskite-type compounds [(CH3)nNH4-n][Mn(N3)3] (n = 1-4) were synthesized and characterized. Structural phase transitions indicating the general lattice flexibility were observed and confirmed by the crystal structures of different phases. These materials show cation-dependent magnetic ordering at up to 92 K and magnetic bistability near room temperature.
