The asymmetric di-aminic compartmental ligand HL5 forms a tetranuclear nickel(II) complex in which the core is assembled from two confacial bioctahedra [Niâ¯Ni, â¼2.90 Ã
]; the open faces of the bioctahedra are joined at the O atoms of two μ-cresolato bridges [Niâ¯Ni, 3.72 Ã
], and the shared faces of the bioctahedra are linked by a tetradentate (μ4,η2)-perchlorate anion and by an unusual tetradentate (μ4,η2)-[H3O2]â bridge.
