Abstract
Schiff base ligand (H2CANPT) was prepared by two steps: first, by the condensation of curcumin with 4-amino antipyrin produces4,4′-(((1E,3Z,5Z,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-diylidene)bis(azanylylidene))bis(1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one) (CANP). Second, by the condensation of (CANP) with L-tyrosine produces2,2′-(((3Z,3′Z)-(((1E,3Z,5Z,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta 1,6-diene-3,5-diylidene)bis(azanylylidene))bis(1,5-dimethyl-2-phenyl-1,2-dihydro-3-H-pyra-zole-4-yl-3-ylidene))bis(azanylylidene))bis(3-(4-hydroxyphenyl)propanoic acid) (H2CANPT). The resulted Schiff comported as hexadentate coordinated with (N4O2) atoms, then it was treated with some transition and non-transaction metal ions, such as (Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Cd(II), Hg(II) chloride and Ag(I) as nitrate to synthesize complexes. All the prepared compounds were identified using FT-IR, UV-visible, elemental analysis (C.H.N), 1H and 13C-NMR, molar conductivity and magnetic susceptibility. Schiff base and its complexes were tested against two types of bacteria (Staphylococcus aureus and Escherichia Coli). Besides, they were tested as dyes on cotton fibres.
