The novel centrosymmetric complex, [In2(pydc)2(pydcH)2(H2O)2] • 2H2O (1), (pydcH2 = 2,3-pyridinedicarboxylic acid) was

synthesized and thoroughly characterized using elemental analysis, IR, 1H NMR spectroscopy and single crystal X...

The proton-transfer systems including pyridine bases and dicarboxylic acids

in aqueous solution and solid states were too considered in recent decade [1,

2], but the bipyridine as base in these systems has been less attention [3]. Also...

COOH/CH3COONa) at pH = 5 and containing an equimolar mixture of Co2+, Fe3+, Cd2+, Cu2+, Zn2+, Ag+ and Pb 2+ metal cations. The organic phase contained the macrocyclic ligand, 1,10-dodecyl-1,10-diaza-18-crown-6 (Kryptofix 22DD) as an ionophore...

Two new coordination compounds of CoII based on pyrazin-2,3-dicarboxylic

acid formulated as (Base)2[CoII(pyzdc)2(H2O)2]·6H2O, (where Base = 2-amino-

4-methyl pyridinium (1); 2-amino-4-methyl pyrimidin-3-ium (2); and pyzdcH2...

of crown ether complexes are affected by the nature and composition of the solvent system [2,3].

The goal of this investigation is to study the effect of the nature and composition of the mixed solvents on selectivity and thermodynamic...
