An unprecedented spin cluster-based network architecture {[NiII 2 (pdaa)(OH)2 (H2 O)]n (H2 pdaa=1,4-phenylene diacetic acid)}, comprising 1D linear chains of NiII ions crosslinked via Ni4 O4 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.
