Synthesis and Characterization of Metal Complexes with New Unsymmetrical Schiff Base Ligand Derived from 2-Aminoethanethiol
A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...
متن کامل3-Acetyl-4-hydroxy-6,7-dimethyl-2H-chromen-2-one
In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H⋯O hydrogen bonds further inter-...
متن کاملSynthesis and antibacterial activity of some Schiff base complexes
Two Schiff bases were synthesized from raceacetophenone: 1) ADS1: 4-ethyl-6-{(E)-1-[(3-nitrophenyl)imino]ethyl}benzene-1,3-diol and 2) ADS3: 4-ethyl-6-{(E)-1-[(2-nitrophenyl)imino]ethyl}benzene-1,3-diol. Then their metal complexes were formed. The metals selected for the preparation of complexes were copper, nickel, iron and zinc. Hence, in total 8 metal complexes were synthesized and screened ...
متن کاملSynthesis and characterization of some transition metal complexes of Schiff base derived from 2,4 - dihydroxybenzaldehyde
Abstract New N2O2 type Schiff base has been designed and synthesized by condensing 2,4 dihydroxy benzaldehyde and α-naphthylamine in ethanol. Solid metal complexes of the schiff base with Cu(II), Ni(II) and Zn(II) metal ion were synthesized and characterized by elemental analysis, magnetic susceptibility, molar conductance, IR, UV-Vis and ‘H NMR spectral studies. The data shows that the c...
متن کاملSynthesis and characterization of some transition metal complexes with new mixed-donor schiff base ligands derived from 2-hydroxynaphthaldehyde
2-[3-(2-Formylnaphthoxy)-2-hydroxypropoxy] naphthaldehyde (1) have been prepared by reaction of 2-hydroxynaphthaldehyde with 1,3-dichloro-2-propanol. New N2O3 macro-acyclic ligands (L1, L2) synthesized from the reaction of (1) with aniline or cyclohexylamine. Ni (II), Co (II) and Cu (II) complexes was prepared from reaction of Schiff-bases with metal chloride and nitrate salts. All of these com...
