Zinc(II) coordination compound with N'-(pyridin-2-ylmethylene)nicotinohydrazide: Synthesis, crystal structure, computational and cytotoxicity studies.

In this work, we report on the synthesis of a novel zinc(II) coordination compound [ZnL] (1), which was readily obtained from the reaction of Zn(OAc)·2HO and N'-(pyridin-2-ylmethylene)nicotinohydrazide (HL) in methanol. Recrystallization of 1 from dimethylformamide under ambient conditions allowed to produce yellow block-like crystals of 1·HO. Complex 1·HO was characterized by FT-IR and H NMR spectroscopy, while its optical properties were studied by UV-vis and spectrofluorimetry in methanol.
