A hexanuclear Ni(II) complex of 1-[(2-carboxymethyl)benzene]-3-[2-pyridine] triazene

A reaction of 1-[(2-carboxymethyl)benzene]-3-[2-pyridine]triazene (HL) and Ni(Ac)2⋅4H 2 O yields crystals of {Ni 6 L 2 L′ 2 (μ 3 -OH) 2 (CH 3 O) 2 (Ac) 2 (H 2 O) 4 } 1 (L′=1-[(2-carboxyl)benzene]-3-[2-pyridine]triazene ion), which has been characterized by single-crystal and powder X-ray diffraction, vibrational spectroscopy, and thermogravimetric (TG) analysis, as well as variable-temperature magnetic susceptibility.► Our interest focused on the design, synthesis and reactivity of new triazenide ligand. ► 1-[(2-carboxymethyl)benzene]-3-[2-pyridine]triazene (HL) was synthesized. ► The reaction of HL and Ni(Ac) 2 ⋅4H 2 O gave a hexanuclear nickel(II) complex.
