Novel chromium(III), manganese(II), iron(III), cobalt(II), nickel(II), copper(II), ruthenium(III), and zirconyl(II) complexes of $N^1,N^2$-bis(3-((3-hydroxynaphthalen-2-yl)methylene-amino)propyl)phthalamide ($H_4L$, 1) have been synthesized and characterized by elemental, physical, and spectral analyses. The spectral data showed that the ligand behaves as either neutral tridentate ligand as in complexes 2-5 with the general formula $[H_4LMX_2(H_2O)]{\cdot}nH_2O$ (M=Cu(II), Ni(II), Co(II), X = Cl or $NO_3$), neutral hexadentate ligand as in complexes 10-12 with the general formula $[H_4LM_2Cl_6]{\cdot}nH_2O$ (M=Fe(III), Cr(III) or Ru(III)), or dibasic hexadentate ligand as in complexes 6-9 with the general formula $[H_2LM_2Cl_2(H_2O)_4]{\cdot}nH_2O$ (M = Cu(II), Ni(II), Co(II) or Mn(II), and 13 with general formula $[H_4L(ZrO)_2Cl_2]{\cdot}8H_2O$. Molar conductance in DMF solution indicated the non-ionic nature of the complexes. The ESR spectra of solid copper(II) complexes 2, 5, and 6 showed $g_{\parallel}$ >g> $g_e$, indicating distorted octahedral structure and the presence of the unpaired electron in the $N^1,N^2$ orbital with significant covalent bond character. For the dimeric copper(II) complex $[H_2LCu_2Cl_2(H_2O)_4]{\cdot}3H_2O$ (6), the distance between the two copper centers was calculated using field zero splitting parameter for the parallel component that was estimated from the ESR spectrum. The antibacterial and antifungal activities of the compounds showed that, some of metal complexes exhibited a greater inhibitory effect than standard drug as tetracycline (bacteria) and Amphotricene B (fungi).

제안 방법
O- ligand environment have been published.12The aim of this work is the preparation, characterization and antimicrobial activity of chromium(III), manganese(II), iron(III), cobalt (II), nickel(II), copper(II), ruthenium(III), and zirconyl (II) complexes of N1,N2-bis(3-((3-hydroxynaphthalen-2-yl)methylene amino)propylphthalamide (H4L).
Microorganisms were spread over each dish by using sterile bent loop rod. The test is carried out by placing filter paper disks with a known concentration of the compounds on the surface of agar plates inoculated with a test organism. Standard antibacterial drug (tetracycline), antifungal drug (Amphotricene B) and solution of metal salts were also screened under similar conditions for comparison.
Molar conductance was measured on a Tacussel type CD6NG conductivity bridge using 10-3 M DMF solutions. Thermal analyses (DTA and TG) were carried out in air using a Shimadzu DT-30 thermal analyzer. The ESR spectra of the solid complexes at room temperature and at 77 K were recorded using a Varian E-109 spectrophotometer (Leicester University, Engeland).
이론/모형
Electronic absorption spectra in the 200-900 nm regions were recorded on a Perkin-Elmer 550 spectrophotometer. Magnetic susceptibilities were measured at 25 ℃ by the Gouy method using mercuric tetrathiocyanato-cobaltate(II) as the magnetic susceptibility standard. The magnetic moments were calculated from the equation: µeff.
The antibacterial and antifungal activities of the ligand and its metal complexes were screened on bacterial and fungal strains using the disk diffusion method. It is important to note that the ligand and most of its metal complexes exhibit more antifungal inhibitory effects than the Standard antifungal drug (amphotricene B) and most of the metal complexes more active than parent ligands and the solution of metal ions.
성능/효과
-bis(3-((3-hydroxynaphthalen-2-yl)methyleneamino)propyl) phthalamide has been synthesized and characterized by elemental and thermal analyses as well as spectroscopic techniques. The analyses data showed that, the ligand behaves as a neutral tridentate, neutral hexadentate, dibasic tridentate or dibasic hexadentate ligand bonded to the metal ion/ions through azomethine nitrogen atoms, protonated or deprotonated hydroxyl groups and protonated or deprotonated amine groups. The metal complexes have a distorted octahedral, square planer or octahedral geometry.
