Complex of
cobalt (II) with nicotinohydroxamic acid (NHA) has been
investigated by spectroscopic method at 25 ± 0.1oC
in aqueous solution of 0.1mol dm-3 ionic
strength. The results reveal the sole formation of 1:2
complex at equilibrium. Spectra and magnetic studies of the
isolated complex indicate octahedral mixed coordination mode
(N.O). Microbial sensitivity test on eight micro-organism
(that is, four gram +ve and four gram - ve bacterial
strains) showed activity.
Key
words:
Complex, hydroxamic acid, spectroscopic investigations,
