Abstract
This work presented synthesis for Schiff base 5-(anthracen-9(10H)-ylideneamino)-2-phenyl-2,4-dihydro-3H-pyrazol-3-one (L3), this ligand was synthesis from reaction for one equivalence of (Anthrone) with one equivalence for 3-Amino-1-phenyl-2-pyrazoline-5-one and its complexes for metal ions (Mn (II), Co (II), Ni (II), Cu (II), Zn (II), Cd (II), and Hg (II)). The Schiff base and its complexes were characterized by C.H.N, FT-IR, UV-Vis, (1H,13C-NMR and Mass spectroscopy only ligand) along with (atomic absorption spectrophotometer, chloride contents, conductivity measurement, magnetic susceptibility, and thermal gravimetric analysis only complexes). Along with to evaluated their biological activity against the types from bacteria and melting point. Based on data of all techniques suggested an octahedral geometry of complexes except complexes Cd (II) and Hg (II), it showed the shape tetrahedral. The results showed biological activity against the kinds from bacteria for synthesized ligand and its complexes.
