Diaquadichloridobis(pyridine-κN)cobalt(II)
The title mol-ecule, [CoCl2(C5H5N)2(H2O)2], has -1 symmetry with the Co(II) ion situated on an inversion centre. The cation has a distorted octa-hedral coordination environment and is surrounded by two N and two Cl atoms in the equatorial plane, while the coordinating water O atoms occupy the axial positions. The crystal exhibits nonmerohedral twinning with two domain states, the volume fractio...
متن کاملSynthesis, Identification and Calculation of Complex Crystallographic Structure of Cobalt (II) with theLigand Heterocyclic Derived from Pyridine
A novel Pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [Co(NO3)2].6H2O has been obtained by the reaction of Pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. The structures of [Co(pydc)(Phen)(H2O)](pydcH2).4H2O receptors, and their complexes were optimized using DFT method at the B3LYP/3-21G** level. The highest occupied molecular o...
متن کاملSolvent Extraction Study of Nickel(II) and Cobalt(II) with l-Phenyl-3-methyl-4-benzoylpyrazol-5-one (PMBP-OH)
The extraction of nickel(II) from aqueous hydrochloric acid solution by I-phenyl 3-methyl-4-benzoylpyrazol-5-one (PMBP-OH) dissolved in carbon tetrachloride has been studied. The extraction of nickel(II) from the aqueous solution in the range of 1.0-5.0 M hydrogen ion concentration has been found to be much higher compared to that of cobalt(II). The extraction of nickel with PMBPOH is simple, f...
