摘要：

Asymmetric 7-formyanil-substituted-imino-4-(4-methyl-2-butanone)-8-hydroxyquinoline-5-sulphonic acid (Schiff bases), react with Co-II, Ni-II and Cu-II ions to give 1:2, 1:1 and 2:1 complexes as established by conductometric titrations in 1:1 DMF:H2O. The complexes were investigated by elemental analyses, molecular weight determinations, molar conductance, magnetic moments, thermal analysis, i.r., u.v.-vis. and e.s.r. spectra. The complexes have an octahedral crystal structure and general formula [ML . (OH2)(2)], where M-II = Co, Ni and Cu, and L = Na[7-X-HL], (-X- = (CH2)(2), (CH2)(3), p-C6H4, o-C6H4). Antimicrobial activity of these new ligands and their transition metal complexes has been screened in vitro on common fungi and bacteria.
