Reaction of the Schiff-base ligand, 3-(4-methylimidazol-5-yl)methylenehydrazonobutan-2-one oxime (H 2 L) with nickel(II) perchlorate hexahydrate in 1:1 molar proportion in methanol gives rise to a tetranuclear nickel(II) compound, Ni 4 L 4 (1) in moderate yield. The compound has been characterized by C, H, N microanalyses, FT-IR, UV–Vis spectra and room temperature magnetic...
Butane-2,3-dione bis(2′-pyridylhydrazone) (BDBPH), a Schiff-base condensate, was synthesized by 1:2 mol ratio condensation of butane-2,3-dione with 2-hydrazino pyridine in dehydrated methanol. BDBPH has been characterised by C, H and N microanalyses, FT-IR, 1H NMR and UV–Vis spectra. Reaction of 1:1 stoichiometric proportion of BDBPH with copper(II)perchlorate hexahydrate in methanol affords a mononuclear...
