Preferred Abstract (Original):

Two tetrahedral mononuclear complexes with a general formula [CoX₂(dmphen)](1–2) (where dmphen is 2,9-dimethyl-1,10-phenanthroline and 1 (X = Br), 2 (X = NCS)) have been synthesized. These complexes are characterized by elemental analysis, IR, UV–visible, TG/DTA and by X-ray diffraction. The calculated electrostatic potential surface of 2 has shown that the electrostatic potential values around sulfur atom is anistropically distributed; the potential values along C–S bond is less negative than the corresponding values in the π-region of S atom. This agrees with the observed geometrical arrangement of C–H⋯S–C hydrogen bonding interactions, the avg. of H⋯S–C angle is 81°. Antimicrobial properties of cobalt(II) complexes was also assessed. Cobalt complexes exhibited significant antibacterial activity against different gram negative and positive human pathogens. The absorption spectrum of these complexes in acetone was modeled by time-dependent density functional theory (TD-DFT).

Preferred Abstract (Original):

We have reported the synthesis of a novel salen ligand and its mononuclear Pd–salen complexes derived from 2-{[2-hydroxy-3-{[(E)-(2-hydroxyphenyl)methylidene]amino}propyl)imino]methyl}phenol. The newly synthesized and isolated Pd(II) complexes have been identified and fully characterized by various physico-chemical studies viz., elemental analyses, IR, UV-Vis, 1H, 13C NMR spectroscopy, electron spray ionization mass spectrometry (ESI-MS) and TGA/DTA studies. The molecular structure of the salen ligand has been ascertained by single-crystal XRD and it is coordinated to Pd(II) ion through two nitrogen and two oxygen atoms. The UV-Vis data clearly suggest a square-planar environment around both the Pd(II) ions. The DNA binding studies of the synthesized compounds has been investigated by electron spectroscopy and fluorescence measurements. The results suggest that Pd(II) complexes bind to DNA strongly as compared to the free ligand. The free salen ligand and its Pd(II) complexes have also been tested against human hepatoma cancer cell line (Huh7) and results manifested exceptional anti-proliferative effects of the Pd(II) complexes. The anti-proliferative activity of Pd(II) complexes has been modulated by specific regulatory genes.

Preferred Abstract (Original):

Two novel and neutral bidentate Palladium(II) complexes of the type, [PdX2(dpme)] (X = Cl 1, OAc 2], have been synthesized from 1,1-bis(diphenylphosphinomethyl)ethene (dpme) ligand and characterized on the basis of elemental analyses, infrared, FAB-MS and 1H-, 13C-, and 31P-NMR spectroscopy. The structure of 1 has been ascertained by single crystal X-ray crystallography and shows cis configuration in a square planar structure while the structural behavior of the dpme ligand through the formation of these complexes has been monitored by 31P{1H} NMR and IR spectra. These Pd(II) complexes have shown a very significant catalytic role in Heck reaction giving high yield under mild condition.

Preferred Abstract (Original):

A binuclear nickel(II) chloride complex with dimethyl-1,10-phenanthroline, di-μ-chloro-bis[chloro(2,9-dimethyl-1,10-phenanthroline)nickel(II)] dimer, has been prepared and its molecular structure determined by X-ray diffraction. The crystal is triclinic, space group P−1, with the Ni(II) in [NiCl2(C14H12N2)]2 coordinated to two N of the phen ligand and three Cl−, one terminal and two bridging. A center of inversion lies midway between two Ni(II). Overall Ni(II) coordination is distorted triangular bipyramidal. The dimer complex was also characterized by elemental analysis, FAB-MS, IR and UV–visible spectroscopy, and thermogravimetric analysis.
