The asymmetric unit of the title compound, [Co(NO3)2L] n , L = N-(pyridine-2-ylmeth-yl)pyridine-3-amine (C11H11N3), contains one CoII centre, two nitrate anions and one L ligand in which the Cpy-C-N-Cpy moiety adopts a trans conformation with a torsion angle of -173.1 (3) Å. The coordination geometry of the CoII atom is a distorted penta-gonal bipyramid. One amine N atom from the L ligand and f...

We report in this communication the facile synthesis of the new tris(thiazolylmethyl)amine TTA ligand and the full characterization in solution and in the solid state of two ferrous complexes, [(TTA)FeCl2] and [(TTA)Fe(OTf)2]. TTA, the first example of a simple tris(thiazolemethyl)amine chelate--the second one only within this class of tripods--exerts a weak ligand field and the tertiary amine ...

The receptors of amine subfamily are specifically major drug targets for therapy of nervous disorders and psychiatric diseases. The recognition of novel amine type of receptors and their cognate ligands is of paramount interest for pharmaceutical companies. In the past, Chou and co-workers have shown that different types of amine receptors are correlated with their amino acid composition and ar...

A new trinuclear Zn (II) complex, [Zn3(L1)4(L2)2(CH3COO)2] (1) (HL1 = 6-phenylpyridine-2-carboxylic acid, L2 bis(4-pyridyl)amine) has been synthesized by NaOH, bis(4-pyridyl)amine and Zn(CH3COO)2•2H2O. The complex 1 also structural characterized elemental analysis single crystal X-ray diffraction. results reveals that is made up of three Zn(II) ions, four L1 ligands, two ligands CH3COO- anions....

By a condensation of aliphatic amine containing adamantyl groups (amantadine, memantine, or 3-amino-1-adamantanol) and 5-fluorosalicylaldehyde, three new Schiff base ligands, HL1–3, were synthesized. One base, zinc(II) chloride, NaOH stirred in anhydrous methanol generating complexes, C34H38F2N2O2Zn (1), C38H46F2N2O2Zn (2), C34H38F2N2O4Zn (3), respectively. These complexes characterized by melt...

Serotonergic ligands have proven effective drugs in the treatment of migraine, pain, obesity, and a wide range of psychiatric and neurological disorders. There is a clinical need for more highly 5-HT2 receptor subtype-selective ligands and the most attention has been given to the phenethylamine class. Conformationally constrained phenethylamine analogs have demonstrated that for optimal activit...

Tridentate amine-imine-phosphine ligands, R2PC5H7NC2H4NEt2 [(R)PNN(H)], where R = Pr(i) or Bu(t) are synthesized using a straightforward protocol of condensation, deprotonation, and addition of a chlorodialkylphosphine. Multinuclear NMR spectroscopy shows the ligands exist exclusively in the enamine tautomeric form in solution. Treating these ligands with RuHCl(PPr(i)3)2(CO) forms the desired c...

Abstract This paper reviews developments in the synthesis of InP quantum dots (QDs) and research on magic-sized clusters (MSCs), which occur as intermediates during growth QDs. We classify MSCs into (1) characterization (2) applications. Several have been developed using low reaction temperatures or strong binding ligands. passivated by carboxylate, amine phosphonate ligands that incorporate he...

Eight new ruthenium and five new osmium p-cymene half-sandwich complexes have been synthesized, characterized and evaluated for antimalarial activity. All complexes contain ligands that are based on a 4-chloroquinoline framework related to the antimalarial drug chloroquine. Ligands HL(1-8) are salicylaldimine derivatives, where HL(1) = N-(2-((2-hydroxyphenyl)methylimino)ethyl)-7-chloroquinolin-...

Abstract A series of neutral C,N,N Au(III) complexes were synthesized with N-(8-quinolinyl)benzamide derivatives or chiral N-[2-(1,3-oxazolin-2-yl)phenyl]benzamide derivatives. The convenient synthesis method for the amide ligands, together their operationally simple complexation by direct C–H auration, permitted changes to both steric and electronic properties promoting catalytic three-compone...
