The complexes of Co (II), Ni (II), Cu (II), Zn (II), Cd (II), Pt (II), and Au (III) were prepared from the complexation reaction between the new Schiff base ligand and metal ions. This ligand(3,4-bis(((E)-1-(2-(((E)-(3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl) methylene) amino) phenyl) ethylidene) amino) phenyl) phenyl) methanone was derived from the condensation reaction of 3,4-diamino benzophenone, 2-amino acetophenone, and pyridoxal hydrochloride. The ligand and its complexes were characterized by C.H.N elemental analysis, Uv-Vis, FT-IR, 1H-NMR and molar conductivity, Atomic absorption, magnetic moment measurements and mass spectra studies. The results of this studies show the coordination sites for the ligand with the metal ion were to be through oxygen of the hydroxyl group, and the nitrogen of azomethine groups. The electronic spectral and magnetic measurement data predict octahedral structure of the complexes, except for Pt (II) and Au (III) complexes were suggested a square planar geometry. All complexes show that nonelectrolytes properties, but Pt (II) and Au (III) complexes are electrolyte nature. New Schiff base ligand and its metal complexes were Screened against bacterial and fungal strains and their preliminary results compounds exhibited the high effect of activity. This may be attributed to the impact of both the chelate effect of new Schiff bases ligand and the role of the metal in these complexes. [ABSTRACT FROM AUTHOR]

New Mixed ligand complexes of Cu (II)then Ni (II) with L1 (1-benzyl 2,3-dialkyl -4-4'chloro Salicylaldene) pyrazole-5-one),(L2) 2-[ (2-Benzothiazolyl) -4-methoxy phenol ],(L3) 1,5-dimethyl-4-((4-methyl-1H-imidazol-2-yl)diazenyl)-2-benzyl-1,2-dihydro-3H-pyrazol-3-one and L5 (1,10,phen) have been synthesized These ion chelates complexes have been brandedwithprimarystudy,IR,1H-NMR,UV-Vis, Molar conductivities, Attractive moments, Spectral data exhibited the(L1,L2) actions as mono anionic tridentate ligand coordinating to the metal ion through(O,N,O),(N,N,O)donor atoms, imine ligand (L4) as monoanionic bidentate coordinating through(O,N)donor atoms,(L3)acts as impartial tridentate ligand coordinating to the metal ion through(N,N,O)and (1,10,phen) acts as neutral didentate ligand coordination from through (N, N). Cu(II) and Ni(II) complexes perform to have an octahedral geometry. Bio-effect studies of the ligand besides to its metal complexes alongside numerous bacteria s.aureus, Escherichia coli, klebsiella pneumonia, Aspergillus.n, Aspergillus. f, Rhizoctoniabataicola and Trichoderma, are stated. Compounds gave the high result of bustle. [ABSTRACT FROM AUTHOR]
