Magnetic Phase Transitions in a Ni(4)O(4)‐Cubane‐Based Metal–Organic Framework

An unprecedented spin cluster‐based network architecture {[Ni(II) (2)(pdaa)(OH)(2)(H(2)O)](n) (H(2)pdaa=1,4‐phenylene diacetic acid)}, comprising 1D linear chains of Ni(II) ions crosslinked via Ni(4)O(4) cubanes, forms under hydrothermal conditions; this 3D coordination network exhibits magnetic ord...

Sumario:An unprecedented spin cluster‐based network architecture {[Ni(II) (2)(pdaa)(OH)(2)(H(2)O)](n) (H(2)pdaa=1,4‐phenylene diacetic acid)}, comprising 1D linear chains of Ni(II) ions crosslinked via Ni(4)O(4) cubanes, forms under hydrothermal conditions; this 3D coordination network exhibits magnetic ordering at 23.9 K as well as a second magnetic ordering process at 2.8 K likely associated with a structural phase transition.
