Plumbum(II) and Zinc(II) Complexes with 5-Chlorosalicylic Acid: Structure and Propertie
Abstract: Two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (H2L5), and 1,10-phenanthroline（phen） and 1,3-Di(4-pyridyl)propane (bpp) as secondary ligands are reported. They are formulated as {[Pb(HL5)2(phen)(H2O)]·H2O}n(1), [Zn2(HL5)4(bpp)2]n(2). All the complexes are characterized by single-crystal X-ray diffractions. Compoud 1 crystallizes in the triclini...
متن کاملSynthesis, Characterization and Biological Studies of 2-(4-Nitrophenylaminocarbonyl)Benzoic Acid and Its Complexes with Cr(III), Co(II), Ni(II), Cu(II) and Zn(II)
Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fung...
متن کاملPhytic Acid Complexes with Mn(II) and Co(II)
Estudos potenciométricos foram realizados para determinar o grau de ligação do ácido fítico com os íons Co(II) e o Mn(II), na ausência de dioxigênio. As constantes de equilíbrio para as principais espécies formadas são relatadas, e os resultados são representados na forma de diagramas de distribuição mostrando a concentração individual dos complexos como uma função do pH. Os valores das constan...
متن کاملChromic Acid Oxidation of Lactic Acid Catalysed by Manganese(II)
B ak o re and N a r a in 1 studied the kinetics of the oxidation of a-hydroxy acids by chromium(VI) and found that addition of Mn(II) decreases the rate of oxidation to one half of that in absence of Mn(II), when the hydrogen ion concentration is in the range 0.1 to 0.4 M. They attributed this to the disproportionation of Cr(IV) by Mn(II) ions. K em p and W a t e r s 2 observed Mn(II) catalysis...
متن کاملA Study on the Extraction of Cd(II), Co(II) and Ni(II) Ions by Bis(2-ethylhexyl)phosphoric Acid and 2-Thenoyltrifluoroacetone
Keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis(2-diethylhexyl)phosphoric acid (DEHPA) and 2-thenoyltrifluoroacetone (HTTA), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable Ni-Cd batteries. The conditions for leach...
