lanthanide(iii) chloro complexes of 4[n-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (hmbaaps) (i) and 4[n-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (tmbaaps) (ii) with the general composition lncl3.2l (ln = la, pr, nd, sm, gd, tb, dy or ho; l = hmbaaps or tmbaaps) are reported. all the complexes were synthesized in ethanolic medium and refluxed the ...

Rhodium complexes with functionalized NHC ligands catalyze the polymerization of phenylacetylene to give very high molar mass stereoregular polymers. Surprisingly, some chloro-complexes are much more active than related cationic precursors also.

Lanthanide(III) chloro complexes of 4[N-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (HMBAAPS) (I) and 4[N-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (TMBAAPS) (II) with the general composition LnCl3.2L (Ln = La, Pr, Nd, Sm, Gd, Tb, Dy or Ho; L = HMBAAPS or TMBAAPS) are reported. All the complexes were synthesized in ethanolic medium and refluxed the ...

The aim of the present study was to synthesize and characterize divalent metal ions Nickel, Copper Zinc complexes 5-chloro 2-furaldehyde thiosemicarbazone. Firstly ligand prepared from reaction between 5-Chloro-2-furaldehyde thiosemicarbazide, second step involved synthesis Ni(II), Cu(II) Zn(II) compounds (ligand or complex) characterized using different analytical techniques such as elemental ...

Physico-chemical properties of 3-chloro-2-nitrobenzoates of Co(II), Ni(II) and Cu(II) were synthesized and studied. The complexes were obtained as monoand dihydrates with a metal ion to ligand ratio of 1 : 2. All analysed 3-chloro-2-nitrobenzoates are polycrystalline compounds with colours depending on the central ions: pink for Co(II), green for Ni(II) and blue for Cu(II) complexes. Their ther...

The crystal and molecular structures of [bis(5-chloro-2methoxybenzoate)tetraaquamanganese(II)], [pentaaqua(5-chloro-2-methoxybenzoato)cobalt(II)] (5chloro-2-methoxybenzoate), [pentaaqua(5-chloro-2-methoxybenzoato)nickel(II)] (5-chloro-2methoxybenzoate) and [aquabis(5-chloro-2-methoxybenzoate)zinc(II)] monohydrate were determined by a single-crystal X-ray analysis. Mn(H2O)4L2 (where L = C8H6ClO3...

The neutral chloro complexes [(g-C5Me5)M(g-NC9H6O)Cl] as well as the cationic aqua complexes [(g-C5Me5)M(g-NC9H6O)(H2O)] (M = Rh, Ir) have been synthesized from the reaction of the dinuclear precursors [(g-C5Me5)MCl2]2 and 8-hydroxyquinoline. The single crystal X-ray structure analysis of [(g-C5Me5)Ir(g-NC9H6O)Cl] reveals for these complexes a piano-stool arrangement with the aromatic ligand, t...

Complexes of the type (OCH2C(CH3)2CH2OB)2S2P(S)OR (where R=Me,Et,Pri,Bui,Ph,CH2Ph) have beensynthesized by the reactions of 2-chloro-1,3,2-dioxaborinanes and potassium salt of O-alkyl (O-aryl)trithiophosphates in 2:1 molar ratio in refluxing benzene. The product are formed as white or light yellowcoloured monomeric solid, soluble in common organic solvents and exhibit high sensitivity towardsat...

Basic studies on concentrated solutions are becoming more and important due to the practical industrial geological applications. The use in redox flow batteries is one of most applications these solutions. Specifically, this paper we investigated high-concentrated copper chloro-complexes with different additives. concentration ligands additives affects physicochemical electrochemical properties...
