Dendrimers functionalized with palladium complexes of n-, n,n-, and n,n,n-ligands

Pyridine, pyridine imine, and bipyridine imine ligands functionalized by a phenol have been synthesized and characterized, in many cases by X-ray diffraction. Several of these N-, N,N-, and N,N,N,-ligands have been grafted onto the surface of phosphorhydr

Ruthenium(II) complexes of aroylhydrazones: structural, electrochemical and electrostatic interactions with DNA

Four Ru(II) complexes with tridentate ligands viz. (4-hydroxy-N′-(pyridin-2-yl-ethylene) benzohydrazide [Ru(L1)(PPh3)2(Cl)] (1), N′-(pyridin-2-yl-methylene) nicotinohydrazide [Ru(L2)(PPh3)2(Cl)] (2), N′-(1H-imidazol-2-yl-methylene)-4-hydroxybenzohydrazide [Ru(L3)(PPh3)2(Cl)] (3), and N′-(1H-imidazol-2-yl-methylene) nicotinohydrazide [Ru(L4)(PPh3)2(Cl)] (4) have been synthesized and characterized. The methoxy-derivative of L3H (abbreviated as L3H*) exists in E configuration with torsional angle of 179.4° around C7-N8-N9-C10 linkage. Single crystal structures of acetonitrile coordinated ruthenium complexes of 1 and 3 having compositins as [Ru(L1)(PPh3)2(CH3CN)]Cl (1a) and [Ru(L3)(PPh3)2(CH3CN)]Cl (3a) revealed coordination of?tridentate ligands with significantly distorted octahedral geometry constructed by imine nitrogen, heterocyclic nitrogen, and enolate amide oxygen, forming a cis-planar ring with trans-placement of two PPh3 groups and a coordinated acetonitrile. Ligands (L1H-L4H) and their ruthenium complexes (1–4) are characterized by 1H, 13C, 31P NMR, and IR spectral analysis. Ru(II) complexes have reversible to quasi-reversible redox behavior having Ru(II)/Ru(III) oxidation potentials in the range of 0.40–0.71?V. The DNA binding constants determined by absorption spectral titrations with Herring Sperm DNA (HS-DNA) reveal that L4H and 1 interact more strongly than other ligands and Ru(II) complexes. Complexes 1–3 exhibit DNA cleaving activity possibly due to strong electrostatic interactions while 4 displays intercalation.

Synthesis, structural characterization, and molecular docking studies of bioactive bismuth(III) complexes with substituted hydrazones

Eight new bismuth(III) complexes (1-8) of substituted hydrazones having general formula; [Bi(RCONHNCHC5H4N)Clx] and [Bi(RCONHNCHC9H6N)Clx], where R = C10H7O (1, and 8)

Synthesis, crystal structures, characterization and catalytic property of manganese(II) complexes derived from hydrazone ligands

A new bromido-coordinated mononuclear manganese(II) complex [MnL1Br2(OH2)] (1), and a new nitrato-coordinated mononuclear manganese(II) complex [Mn(L2)2(ONO2)(OH2)]NO3

A novel supramolecular polymer fabricated via stronger hydrogen-bonding interactions between substituted amide groups: Design, synthesis, properties and mechanism

A novel difunctional monomer, 1,12-di(2-pyridine carbaldehyde-4′-hydrazinephenylate) dodecane (defined as DPCHP-DODE), was designed and synthesized through a two-step reaction process. The chemical structure of DPCHP-DODE was confirmed by a 1H

Dynamic acylhydrazone metal ion complex libraries: A mixed-ligand approach to increased selectivity in extraction

The dynamic nature of metal-ligand interactions facilitates the formation of metal ion acylhydrazone complex libraries. From these libraries, metal ion complexes with two different types of ligands (1-14; R1≠R2) are shown to have sup
