Synthesis, Characterization and Biological Study of Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) Complexes with a New Tetradentate Schiff Base Ligand

الملخص

At this paper we describe the synthesis of new Schiff Base (L) : 3,3`-(benzene-
1,4-diyldinitrilo) bis (1,3-dihydro-2H-indol-2-one).
The product (L) was characterized by (FT-IR), (UV-Vis) spectroscopy and
elemental analysis (C. H. N). (L) has been used as aligand to prepare a number of metal
complexes with Cr(III), Mn(II, Co(II), Ni(II), Cu(II) and Zn(II). The prepared complexes
were isolated and characterized by (FT-IR) and (UV-Vis) spectroscopy, elemental
analysis (C. H. N) flame atomic absorption technique, as well as magnetic susceptibility
and conductivity measurement. The Schiff base (L) and its complexes, with different
concentration, have been screened for their (In-Vitro) antibacterial on (E. coli) and
(Bacillusubtilis) and antifungal (A. niger) and (P. chrysogenum) activities by using
different concentration.
