Synthesis and characterization of some mixed-ligand picrate complexes of nickel(II) involving heterocyclic nitrogen donors

The present communication describes the synthesis of some mixed-ligand hexacoordinated picrato complexes of nickel(II) of the composition [Ni(PA)2(L-L)2], where PAH = picric acid and L-L = 2-aminoben-zothiazole (ABZT), 2-(2?-aminophenyl)benzothiazole (2?-AMPHBZT), 2-(3?-aminophenyl)benzothiazole (3?-AMPHBZT), bipyridine (bpy), o-phenanthroline (phen) or 2,6-bis(benzimidazyl)pyridine (BBZLPY). These complexes were obtained by the interaction of nickel(II) picrate with the corresponding ligands L-L in methanol. The resulting compounds have been characterized by elemental analyses, magnetic, molar conductance and decomposition temperature measurements, electron spin resonance, infrared and electronic spectral studies. All the complexes are thermally stable and behave as non-electrolytes. An octahedral structure has been tentatively proposed for these complexes.

Perfluoroalkylation of Square-Planar Transition Metal Complexes: A Strategy to Assemble Them into Solid State Materials with a pi-pi Stacked Lamellar Structure

Formation of pi-pi stacked lamellar structure is important for high performance organic semiconductor materials. We previously demonstrated that perfluoroalkylation of aromatics and heteroaromatics was one of the strategies to design organic crystalline materials with pi-pi stacked lamellar structures while improving air stability as a result of the strong electron withdrawing ability of perfluoroalkyl substituents. Square-planar transition metal complexes with large pi-conjugated ligands are also an important category of semiconductor materials. We have perfluoroalkylated square-planar transition metal complexes, leading to the formation of a pi-pi stacked lamellar crystal packing motif in the solid state. Here we report six crystal structures of Pd and Pt complexes with bis-perfluorobutylated catechol ligand as one of the two ligands that bonds to the metal centers. This structural design possesses similar molecular topology when compared to perfluoroalkylated aromatics and heteroaromatics we have reported previously, again, demonstrating the steering power of the perfluoroalkyl substituents in engineering organic and organometallic solid state materials.

Synthesis, characterization, and ethylene oligomerization and polymerization of [2,6-bis(2-benzimidazolyl)pyridyl]chromium chlorides

A series of [2,6-bis(2-benzimidazolyl)pyridyl]chromium chlorides have been synthesized and characterized by elemental analysis and IR spectroscopy, along with X-ray diffraction analysis for the structures of Cl and C7. When methylaluminoxane (MAO) was employed as the cocatalyst, the chromium complexes showed high activity for ethylene oligomerization and polymerization. Oligomers were produced with high selectivity for alpha-olefins, and polyethylenes were generated with extremely broad molecular weight distributions. In the presence of diethylaluminum chloride (Et2AlCl), these chromium complexes showed moderate activity for ethylene polymerization and produced high-molecular-weight linear polyethylene.

Acetate recognition by 2,6-bis(2-benzimidazolyl)pyridine

2,6-Bis(2-benzimidazolyl)pyridine, bbp, a simple tridentate ligand, is employed as a receptor for the recognition of anions. The binding of anionic guest species with bbp can be studied in short duration using UV/vis spectroscopy, fluorescence spectroscopy and 1H NMR techniques at very low concentrations. The results obtained from the above spectroscopic techniques indicate that 2,6-bis(2-benzimidazolyl)pyridine is an efficient anion receptor providing chemical shift and optical modification based signals for the detection of acetate ions.

Synthesis and Proton Transfer-linked Redox Tuning of Ruthenium(II) Complexes with Tridentate 2,6-Bis(benzimidazol-2-yl)pyridine Ligands

New ruthenium complexes of two tridentate ligands 2,6-bis(benzimidazol-2-yl)pyridine (L7) and 2,6-bis(1-methylbenzimidazol-2-yl)pyridine (L8) have been synthesised.Proton and (13)C NMR spectroscopy served well for their characterization, and the observed change.Proton chemical shift yields information about the electron distribution accompanying deprotonation of the ligands.The (n+) chelate acts as a tetrabasic acid, with pKa ranging from 2.5 to 10.7, depending on the ruthenium oxidation state.The absorption spectra and oxidation potentials areconsequently sensitive to solution pH and to solvent.The proton-coupled oxidative electron-transfer reactions of the complexes afford stable higher oxidation states such as Ru(IV).The properties of the complexes are discussed ion comparison to those of previously reported bis(tridentate ligand)ruthenium compounds.

Thiourea recognition by 2,6-bis(2-benzimidazolyl)pyridine using spectroscopic techniques and DFT

Recognition of thiourea by 2,6-bis(2-benzimidazolyl)pyridine, bbp, a neutral tridentate ligand was studied by UV visible and fluorescence spectroscopic techniques. FTIR spectroscopy and supportive DFT calculations established that, thiourea molecule, while bound to the binding site of bbp took up a near perpendicular orientation to the plane of the receptor. While forming the complex, the two imidazole H atoms present in the binding site of bbp formed two weak interactions with S atom of thiourea, which has low electronegativity. Moreover, bigger size of S atom restricted approach of thiourea inside the binding site. Stability of the bbp:thiourea complex basically increased as one of the imine H atom of thiourea is involved in a hydrogen bond with the pyridine N atom of bbp, which forced the near perpendicular orientation of thiourea on the plane of bbp. This binding mode is significantly different from the binding mode of urea with bbp as reported earlier.
