The self-assembly and magnetic properties of a Ni(II)(8)(mu(4)-hydroxo)(6) cube with mu(2)-pyrazolate as an exogeneous ancillary ligand

A novel octanuclear hydroxonickel(II) complex possessing a unprecedented cube molecular structure with eight Ni(II) ions at each vertex, six mu(4)-OH- groups closing each face and twelve exo-bidentate pyrazolate ligands (mu(2)-pz) spanning each edge, has been synthesized and its magnetic properties investigated.
