Abstract:
The synthesis of a series of adducts of 2-amino-1-ethylbenzimidazole (L1) in Cu(II), Co(II), Zn(II) and Ni(II) chelates of the N, N, S tridentate basic form of the tosylamino functionalized pyrazol containing Schiff base N-[2-[[3-methyl-1-phenyl-5-thioxo-pyrazole-4-ylidenemethyl]amino]phenyl]-4-methylbenzenesulfonamide (H2L) with common formula [M(L)L1] was performed. The compounds were characterized with C, H, N elemental analysis, FT-IR, 1H NMR, X-ray absorption spectroscopy and magnetic measurements. Crystal structure of nickel complex [Ni(L)L1] showed that the 2-amino-1-ethylbenzimidazole co-ligand is coordinated through the endocyclic nitrogen atom of pyridine type. The assignment and the nature of the electronic transitions observed in the UV–Vis spectra of chelates were analyzed using time-dependent (TD) DFT calculations.
