“…The development of the field of bioinorganic chemistry has increased the interest in Schiff base complexes, since it has been recognized that many of these complexes may serve as models for biologically important species (e.g. [1,2]). Coordination compounds derived from aroylhydrazones have been reported to act as enzyme inhibitors and are useful due to their pharmacological applications (e.g.…”

The crystal structures of two novel Schiff base hydrazones have been determined by means of the X-ray diffraction. These compounds: Both molecules have very similar bond lengths and angles pattern, even in the differently substituted phenyl ring. However, the conformations of the molecules differ significantly, the more crowded molecule 1 is much more folded than 2. The dihedral angle between the terminal ring planes is 56.17(6)°in 1 while in 2 it is as small as 2.83(14)°. In both structures relatively short and linear N-HÁÁÁO hydrogen bonds (created by the best available hydrogen bond donor and acceptor) connect molecules into the chains along the unit cell parameter of ca. 8 Å in length. The next stage of the crystal architecture determination, the secondary interactions, are however quite different: in 1 there are almost solely dispersion van der Waals interactions while in 2 some more specific C-HÁÁÁF and C-HÁÁÁp interactions are also involved in the crystal packing.

“…Interest in the study of Schiff base hydrazones has been growing because of their antimicrobial, anti-tuberculosis, and anti-tumour activity [1][2][3][4][5][6][7][8][9][10][11][12]. Schiff bases play an important role in inorganic chemistry, as they easily form stable complexes with most transition metal ions.…”

A series of new copper(II), cobalt(II), nickel(II), manganese(II), iron(III), and uranyl(VI) complexes of the Schiff base hydrazone 7-chloro-4-(benzylidenehydrazo)quinoline (HL) were prepared and characterized. The Schiff base behaves as a monobasic bidentate ligand. Mononuclear complexes with the general composition [ML 2 (Cl) m (H 2 O) 2 (OEt) n ]·xEtOH (M = Cu(II), Co(II), Ni(II), Mn(II), Fe(III) or UO 2 (VI); m and n = 0-1; x = 1-3) were obtained in the presence of Li(OH) as a deprotonating agent. The nature of bonding and the stereochemistry of the complexes have been deduced from elemental analyses, infrared, electronic spectra, magnetic susceptibility and conductivity measurements. An octahedral geometry was suggested for all the complexes except the Cu(II) and UO 2 (VI) ones. The Cu(II) complex has a square-planar geometry distorted towards tetrahedral, while the UO 2 (VI) complex displays its favored heptacoordination. The Schiff base ligand, HL, and its complexes were tested against one strain Gram +ve bacteria (Staphylococcus aureus), Gram -ve bacteria (Escherichia coli), and Fungi (Candida albicans). The prepared metal complexes exhibited higher antibacterial activities than the parent ligand and their biopotency is discussed.

“…33). The new ligands and their metal complexes were screened for their antimicrobial activity and the results showed significant biological activity of the prepared complexes [82]. Some new imine complexes of copper(II) had been synthesized by Naeimi et al [83] from the condensation of 2-hydroxynaphthalene-1-carbaldehyde with various amines under template condition (Scheme-XII).…”

2-Hydroxynaphthalene-1-carbaldehyde is a key predecessor to an assortment coordinating agent and the Schiff bases derived from these ligands played a unique role in the development of important biomolecules which exhibit a widely range as a model system for biological macromolecules. Schiff bases formed from o-hydroxy aromatic ketones and aldehydes are stellar design for the study of keto-enol tautomerism in liquid and solid state. The metal-Schiff base complexes obtained from 2-hydroxynaphthalene-1-carbaldehyde had been revealed to show a broad area of biological effectiveness, catalytic reaction, sensors, selective electrodes and fluorescent.
