A Cu-based organic-inorganic perovskite framework exhibits high-temperature ferroelectricity with strong magnetoelectric effects. Both electric field control of magnetization and magnetic field control of polarization are realized. Theoretical calculations suggest that a new mechanism of hybrid improper ferroelectricity arising from the Jahn-Teller distortions of magnetic metal ions and tilting of the organic cations are responsible for the peculiar multiferroic behaviors. A Cu-based perovskite organic-inorganic framework showing high-temperature improper ferroelectricity. ((c) 2015 WILEY-VCH Verlag GmbH &Co. KGaA, Weinheim)
