Here, we report the synthesis of a Schiff-base mixed-ligand complex of cadmium(ІІ) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. The complex formula is [Cd(3-bpdh)(3-bpdb)Cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. The structure of mixed-ligand complex (1) wa...

We aimed to synthesize the phenylhydrazone derivative of 4benzoyl-3-methyl-1-phenyl-5-pyrazolone which is a novel Schiff base. The ligand was synthesized in three stages. 3-methyl-1-phenyl-5-pyrazolone was synthesized as reported in the literature. (Ref. Vogel). This was benzoylated at the 4position to get 4benzoyl-3-methyl-1phenyl-5-pyrazolone (ref. Jesen’s procedure). This was condensed with ...

In the title Schiff base complex, [Zn(C(14)H(9)Br(2)FNO)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two O and two N atoms from two symmetry-related bidentate Schiff base ligands in a compressed tetrahedral geometry. The bond lengths and bond angles are within normal ranges. The dihedral angle between the least-squares planes of the aromatic rings within eac...

A novel Schiff-base ligand (L: 2-[(4-chloro-2-oxo-2H-chromen-3-ylmethylene)-amino] propionic acid) was prepared from the reaction of 4-chloro3-formylcoumarin and alanine amino acid. Copper (II) complex was synthesized from the reaction of the ligand with Cu (OAc)2. H2O in ethanol. The ligand and its metal complex were characterized by elemental analysis (CHN), ICP, thermal analysis (TGA), Fouri...

Acylhydrazine derived furanyl and thienyl Schiff bases and their Cu(II) complexes have been prepared and characterized on the basis of their physical, spectral and analytical data. The preferred enolic form of the Schiff base function as a tetradentate ligand during coordination to the metal ion yielding a square planar complex. The Schiff bases and their complexes with different anions were te...

The asymmetric unit of the title compound, [Cd(2)Cl(2)(NCS)(2)(C(15)H(15)NO(2))(2)](n), contains the Schiff base 2-[(4-methyl-phenyl-imino)meth-yl]-6-methoxy-phenol (HL) ligand, one thio-cyanate and one chloride ligand coordinated to a cadmium centre. The cadmium centers are linked to each other via two thio-cyanate and two chloride bridges alternately, resulting in centrosymmetric zigzag chain...

The Complexes of the type ML2 and M′L [where M= Cu(II), Co(II), Ni(II) and Mn(II); M′= Zn(II), Cd(II) and Hg(II)] with the Schiff base ligand (HMeOQMAMQ) L=3-[(2-hydroxy-6-methoxyquinolin-3-ylmethylene)amino]-2-methyl-3H-quinazoline-4-one, have been synthesized. Their characterizations have been done by elemental analysis, conductance data, magnetic susceptibility measurements, H NMR, electroni...

A novel and simple approach to the synthesis of macrocyclic Schiff base ligand resulted from the condensation of bisaldehyde and ethylenediamine was prepared (7, 8, 15, 16, 17, 18-hexahydrodibenzo (a, g) (14) annulene) (L) and its complexes were synthesized and characterized using different physicochemical studies as elemental analysis, FT-IR, H NMR, conductivity, magnetic properties, thermal a...

In the title compound, [ZnBr(2)(C(17)H(14)Cl(4)N(2))], the Zn(II) ion is bonded to two bromide ions and two N atoms of the diimine ligand and displays a moderately distorted tetra-hedral coordination geometry. The Schiff base ligand acts as a chelating ligand and coordinates to the Zn(II) atom via two N atoms.
