A new hydrazone derivative compound has been synthesized and characterized by IR, 1 H-NMR, 13 C-NMR and UV-vis. spectroscopy techniques, elemental analysis and single-crystal X-ray diffraction (XRD). The new compound crystallizes in monoclinic space group C2/c. In addition to the crystal structure from X-ray experiment, the molecular geometry, vibrational frequencies and frontier molecular orbitals analysis of the title compound in the ground state have been calculated by using the HF/6-31G(d, p), B3LYP/6-311G(d, p) and B3LYP/6-31G(d, p) methods. The computed vibrational frequencies are used to determine the types of molecular motions associated with each of the observed experimental bands. To determine conformational flexibility, molecular energy profile of (1) was obtained by semi-empirical (AM1) calculation with respect to a selected degree of torsional freedom, which was varied from -180 o to +180 o in steps of 10 o . Molecular electrostatic potential of the compound was also performed by the theoretical method.

“…Nowadays, considerable attention has been paid to the Schiff bases and their metal complexes. Aromatic Schiff bases or their metal complexes catalyze reactions on oxygenation [4], hydrolysis [5], electroreduction and decomposition [6]. Some of Schiff base derivatives or their metal complexes show antibacterial activity against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Proteus vulgaris pathogenic bacteria [7,8], possess effective antifungal [9], anti-HIVactivity [10] and antiviral activity [11].…”

KEYWORDSThe complexation behaviour of some salophen,s derivatives with few transition and heavy metal cations in N,N'-dimethyl formamid as nonaqueous solvent at 25 o C and 0.05 M tetra ethylammonium perchlorate to investigate the effect of structure were studied by spectrophotometric method. The formation of complexes between ligands and metal ions of the types ML, ML2 or M2L was observed. The overall stability constants of such complexes were evaluated by computer refinement of absorption-mole ratio data using the KINFIT program.

“…Schiff bases constitute an interesting class of chelating agents, capable of coordination with one or more metal ions to form mononuclear as well as polynuclear metal complexes [1,2]. Some of these applications could be found in analytical chemistry and serve as biochemical models [3,4]. Most Schiff bases have antibacterial, anticancer, anti-inflammatory and antitoxic activities and the sulfur-containing Schiff bases are particularly effective [5].…”

A new compound of (C 27 H 25 N 3 S) has been synthesized and characterized by 1 H NMR, 13 C NMR, IR, UV-Visible spectroscopy, and single crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P2 1 /c and crystals of (I) were found approximately 0.5:0.5 ratio to be twinned. The crystal structure is stabilized by N-HÁÁÁN inter molecular hydrogen bonding. In addition to the molecular geometry and dimeric structure from X-ray experiment, the optimized molecular geometry for monomer and dimer, vibrational frequencies, atomic charges distribution, and total energies of the title compound in the ground state have been calculated using ab initio method. Density Functional Theory (B3LYP) and Hartree-Fock (HF) methods with basis sets 6-31G(d, p) and 3-21G were used in the calculations. Calculated frequencies are in good agreement with the corresponding experimental data. UV-Vis absorption spectra of the compound have been ascribed to their corresponding molecular structure and electrons orbital transitions.
