1D ferromagnetic Dy(III) compound showing supramolecular four-connecting rod-packing architecture

A new Dy(III) compound, namely Dy(4-nitrobenzoato)3(H2O) (1) featuring a 1D chain-like structure, was obtained by hydrothermal self-assembly of Dy(ClO4)3 and 4-nitrobenzic acid. The magnetic studies suggest weak intrachain ferromagnetic interactions and the magnetic data were interpreted by means of non-critical scaling theory with the parameters of C1 = 13.79 cm3mol−1K, E1 = 0.26 K, C2 = 0.58 cm3mol− 1K, E2 = − 34.86 K.
