| Popis: | The reaction of aroylhydrazone ligand H2L with Ni(II) metal ions afforded, upon crystallization under aerobic conditions, a novel heptanuclear Ni(II) cluster without this ligand (template effect of aroylhydrazone ligand). The heptanuclear [NiII7] compound 1 displays a metallic core which can be presented as a vertex-shared dicubane structure. Noteworthy, (i) this ligand is used for the first time in coordination chemistry, and (ii) this cluster does represent the first example in Nickel chemistry that possesses this topology with a structure not supported by any organic bridging ligand. |
