The Metal Chelates of Heterocyclic /3-Diketones and their Derivatives, Part IV New Mixed Ligand Tetrakis Complexes of Lanthanides Derived from tris-Acetylacetonates and Some 4-Acyl Pyrazolones
The preparation of Lanthanon octa-coordinated mixed chelates with different types of ligands is uncommon. Thompson and Loraas [1] have shown the presence of octacoordinated mixed chelates in solution. Recently, Dutt and Sur [2] have actually isolated several mixed tetrakis compounds of La, Pr, Nd, and Sm with three acetylacetone (Acac) molecules, the other ligands being propionylacetone or benz...
متن کاملProduction of siderophore type chelates by mixed bacterioplankton populations in nutrient enriched seawater incubations
Siderophore type chelates were isolated from nutrient enriched seawater collected from coastal and near shore environments and detected using a novel high performance liquid chromatography – electrospray ionisation – mass spectrometric technique. Seawater was enriched with added glucose, ammonia and phosphate, and incubated for four days. Seven different siderophore type compounds were detected...
متن کاملAnnihilation electrogenerated chemiluminescence of mixed metal chelates in solution: modulating emission colour by manipulating the energetics
We demonstrate the mixed annihilation electrogenerated chemiluminescence of tris(2,2'-bipyridine)ruthenium(ii) with various cyclometalated iridium(iii) chelates. Compared to mixed ECL systems comprising organic luminophores, the absence of T-route pathways enables effective predictions of the observed ECL based on simple estimations of the exergonicity of the reactions leading to excited state ...
متن کاملUse of Iron Chelates
U s e of chelating agents--especially the new compound Fe 1 3 8 t o correct iron chlorosis by effectively supplying iron to plants has proved promising in a series of experiments. All plant species tested-but not all individual plants-responded to treatment, and some of the individuals within species did respond with retreatment. Treatment responses in the field have lasted from two to six mont...
متن کاملPhosphonated chelates for nuclear imaging.
A series of bis-, tris- and tetra-phosphonated pyridine ligands is presented. In view of their potential use as chelates for radiopharmaceutical applications, the physico-chemical properties of the ligands and of their Co(II), Ni(II), Cu(II), and Zn(II) complexes were studied by means of potentiometry and UV-Vis absorption spectroscopy. The pKa values of the ligands and of the complexes, as wel...
