A Study of Metal Complexes of (E)-N-{(2-hydroxynaphthalen-1-yl) methylene} Furan-2-Carbohydrazide

Three mononuclear metal complexes of Co2+, Ni2+ and Cu2+ metal ions with (E) -N’-{ (2-hydroxynaphthalen-1-yl) methylene} Furan-2-carbohydrazide (SBL) were synthesized by condensation reaction. All the newly compounds are characterized by spectroscopically using IR spectroscopy, UV-Vis spectroscopy, mass spectroscopy, 1 H & 13C NMR, micro elemental analysis, magnetic susceptibility and conductivity measurements. The spectral data suggested that SBL acted as monobasic tridentate towards central metal ions with ONO donor atoms. The result of molar conductance values and magnetic susceptibility apparent 1: 2 metal to ligand stoichiometry and octahedral geometry for all metal complexes. All the synthesized compounds were also screened for antimicrobial activity against Staphylococcus aureus (ATCC 25923), Staphylococcus aureus (ATCC 3160) bacterial species and Candida albicans (227) and Staphylococcus cereviscae (361) fungal species.
