The title complex, [Cu(C(12)H(16)NO(3))(2)], adopts a distorted square-planar coordination geometry with the Cu(II) ion situated on a crystallographic inversion center. The two Schiff base ligands are coordinated in a trans fashion. In the crystal structure, non-classical inter-molecular C-H⋯O hydrogen bonds involving the ether O atoms link the Schiff base mol-ecules into a two-dimensional netw...

In the title complex, [CuEr(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is coordinated in a square-planar environment by two O atoms and two N atoms of a Schiff base ligand. The Er(III) ion is bis-chelated by three nitrate ligands and coordinated by four O atoms of the Schiff base ligand in a slightly distorted bicapped square-anti-prismatic environment.

In the present research work, four new heterocyclic Schiff base ligands (1–4) were synthesized by condensation of 4-(4-amino-5-mercapto-4H-1,2,4-triazol-3-yl)phenol with salicylaldehyde derivatives in 1:1 molar ratio. The allowed for complexation Co(II), Ni(II), Cu(II), Zn(II) metal ions. structure newly compounds (1–20) was elucidated help various spectral and physicochemical techniques. Spect...

The vanadium(V) complexes have been investigated as potential anticancer agents which makes it essential to evaluate their toxicity for safe use in the clinic. large-scale synthesis and acute oral mice of oxidovanadium(V) Schiff base catecholate complex, abbreviated [VO(HSHED)dtb] containing a redox-active ligand with tridentate (HSHED = N-(salicylideneaminato)-N’-(2-hydroxyethyl)-1,2-ethylened...

Schiff bases are versatile ligands and known to be synthesized from the condensation of an amino compound with carbonyl compounds. These compounds along with their metal complexes are considered to be an important as catalysts in various biological processes. Also Schiff base complexes are gaining popularity among the various industries including polymers, dyes and pharmaceutical. This review s...

A new heterocyclic Schiff base ligands and their complexes have been synthesized from 4-aminoantipyrine, thiophene-2-Carboxaldehyde and 2-amino benzoic acid. The ligands and its transition metal complexes of Cu (II), Co (II), Ni (II) and Zn (II) are characterized by UV, FTIR NMR and Mass studies. The antibacterial and antifungal activity of the ligands and the metal complexes were tested.

Short Abstract 3-Formylsalicylic acid (Hfsal) covalently bound to chloromethylated polystyrene (PS) cross-linked with 5% divinylbenzene reacts with DL-alanine and L-isoleucine to give the Schiff-base tridentate ligands PS-H2fsal-DL-Ala and PS-H2fsal-L-isoleu, respectively. These anchored ligands on reaction with VOSO4 and Cu(CH3COO)2.H2O form complexes PS-[VO(fsal-DL-Ala)(H2O)], PS-[Cu(fsal-DLA...
