Two tridentate and one bidentate binding strands have been anchored on a carbon atom to provide a new unsymmetrical tripodal ligand L for Ln(III) coordination. The ligand itself adopts a single conformation in solution stabilized by intramolecular hydrogen bonds evidenced in the solid state. The reaction of L with trivalent lanthanides provides different coordination complexes depending on the ...

Unsymmetrical (N,C,E)-type pincer ligand precursors [ and : E = S/Se] with an indole core were synthesized for the first time by the condensation of 1-(2-phenylsulfanyl/selenylethyl)-1H-indole-3-carbaldehyde with benzyl amine. The synthetic protocols are easy and give good yields (>85%). and on reaction with sodium tetrachloropalladate(ii) in the presence of CH3COONa result in complexes [Pd(/-H...

In the title compound, [Ru(C(13)H(7)Cl(2)N(5))(C(15)H(11)N(3))](PF(6))(2)·2CH(3)CN, the Ru(II) atom is coordinated in a distorted octa-hedral geometry by a tridentate 2,2':6',2''-terpyridine ligand and a tridentate 2,6-bis-(5-chloro-pyrimidin-2-yl)pyridine ligand. Least-squares mean-plane distortions of only 1.72 (2) and 2.91 (2)° of the pyrimidyl rings with respect to the central pyridine are ...

Five rare earth complexeslanthanum(III),praseodymium(III),neodymium(III), samarium(III) and europium(III) have been synthesized from Schiff base ligand (N,N-bis (2-hydroxy-1-naphthylidene) acetylhydrazone). The complexes were characterized based on elemental analysis, molar conductance, ultraviolet, infrared, mass, thermogravimetric and powder X-ray diffraction studies. Infrared spectra sug...

We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....

In the title complex, [Co(C(16)H(15)N(2)O)(C(10)H(9)O(2))(N(3))], the Co(II) atom adopts an octa-hedral coordination geometry by a tridentate Schiff base, a bidentate benzoyl-acetonate and an azide ligand. The imine N atom of the tridentate ligand is trans to the benzoyl O atom of the bidentate ligand and the azide ligand is trans to the acetyl O atom of the bidentate ligand. Non-classical intr...
