Complexes of nickel(II) of N,N’-disalicylidene-3,4-diaminotoluene(H2L1), N,N’-bis(3,5-di-tert-butylsalicylidene)-1,3-diaminopropane(H2L2),tetrathiafulvalene-N,N’-phenylene bis (salicylideneimine)(H2L3), o-hydroxybenzaldehyde, o-hydroxyacetophenone ethylene diamine (H2L4) and 1-phenylbutane-1,3-dionemono-S-methylisothio- semicarbazone with 5-phenylazo- o-hydroxybenzaldehyde (H2L5) have been synthesized and characterized by elemental analysis, electronic, (Infra-Red) IR, 1H NMR, magnetic susceptibility measurement, molar conductance and thermal studies. The complexes are found to be non- ionic in nature. The analytical studies show tetrahedral, square planar and octahedral geometries of the complexes. The complexes have been found to posses 1:1 (M:L) stoichiometry. The bioefficacy of the ligands and their complexes have been examined against the growth of bacteria in vitro to evaluate their anti-microbial potential.
