      Sánchez-Andújar, Manuel; Yáñez-Vilar, Susana; Pato-Doldán, Breogán; Gómez-Aguirre, Claudia; Castro-García, Socorro; Señarís-Rodríguez, M. A. (American Chemical Society (ACS), 2012-05-30)
      [Abstract] In this work, we show that the hybrid material Co2(1,4-bdc)2(dabco)•[4DMF•1H2O], shows an apparent colossal dielectric constant at room temperature (r5000 at 300 K for =100 Hz). Nevertheless, such response ...

    • Coexistence of magnetic and electrical order in the new perovskite-like (C3N2H5)[Mn(HCOO)3] formate

      [Abstract] In this work we further the structural characterization of the recently discovered (C3N2H5)[Mn(HCOO)3] metal–organic framework with perovskite-like structure, and we present its magnetic and dielectric properties ...

    • Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃]
