In the title complex, [Cu(C(14)H(11)NO(4))(C(12)H(8)N(2))], the tridentate Schiff base ligand is derived from the condensation of 2-hydr-oxy-1-naphthaldehyde and l-serine. The Cu(II) atom is five-coordinated by one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal geometry. In the crystal structure, the combin...

The V(IV) atom in the title complex, [V(C(11)H(13)BrClN(2)O)(C(5)H(7)O(2))O], is six-coordinated by one phenolate O, one imino N and one amino N atom of the tridentate anionic Schiff base ligand, by one oxide O atom, and by two O atoms of an acetyl-acetonate anion, forming a distorted cis-VN(2)O(4) octa-hedral coordination geometry. The deviation of the V atom from the plane defined by the thre...

In the title compound, [HgBr(2)(C(22)H(28)N(2)O(6))], the Hg(II) ion is bonded to two Br(-) ions and two N atoms of the chelating Schiff base ligand in a distorted tetra-hedral geometry. The Schiff base ligand adopts an E,E conformation. The dihedral angle between the planes of the two halves of the central N,N'-dimethyl-ethylenediamine part of the ligand is 2.3 (11)°. The crystal studied was t...

in this paper, plate-like nio nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (ii) schiff base complex as new precursor. first, the nickel (ii) schiff base precursor was prepared by solid-state grinding using nickel (ii) nitrate hexahydrate, ni(no3)2∙6h2o, and the schiff base ligand n,n′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

Reaction of excess cyanide with a ruthenium(VI) nitrido complex bearing a tridentate Schiff base ligand produces a novel tricyanoruthenium(III) complex in which nucleophilic substitution of an imine hydrogen of the Schiff base by cyanide has occurred, this complex is a useful building block for the construction of 3d-Ru(III) magnetic materials.

In the title compound, [Mn(NCS)(2)(C(17)H(20)N(4))], the Mn(II) atom is six-coordinated by the N,N',N'',N'''-tetra-dentate Schiff base ligand and by two trans-N atoms from two thio-cyanate anions, forming a distorted octa-hedral geometry. The dihedral angle between the aromatic rings of the Schiff base is 9.5 (3)°.

The pyridine-coordinated Cu(II) atom in the title Schiff base complex, [Cu(C(15)H(11)N(3)O(5))(C(5)H(5)N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.

A new series of transition metal complexes of Co(II), Ni(II), Cu(II) and Zn(II), has beensynthesized from the Knoevenagel condensate Schiff base ligand(L) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. Structural features were determinedby spectral and analytical techniques. Square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

Schiff base ligand (E)-4-[(hydroxyl phenylimino)methyl]benzene-1, 2-diol (H3L) was prepared from the condensation reaction of Protochatechu aldehyde (3, 4-dihydroxybenzaldhyde) with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides and Fe(III) and Zn(II) nitrates in 2M:1L molar ratio, the five new neutral complexes were prepared. The character...

A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...
