Transition metal complexes

This modeling is performed on an experimental data set of complexes, where the metal ions of these complexes include transition ion metals and lanthanide ion metals. We use these models to develop a series of new thiosemicarbazone and their complexes; simultaneously, the complexes are worked out the stability constants from the novel models.

In recent times many research activities have been carried out to prove the metal ion detection ability of Schiff bases. [13,14] In the present study, a new Schiff base has been synthesized from 5-bromo-2- hydroxybenzaldehyde and naphthalene-1,8-diamine and it is complexated with Co(II), Ni(II), Cu(II) and Zn(II) ions. The biological application of all the compounds has been analyzed and metal ions recognition property of the Schiff base has also been studied.

Ebook "π-Electron magnetism from molecules to magnetic materials" deal with organic molecule-based magnetic materials in which the unpaired spins of the building-block units are located on rc-orbitals conferring special characteristics that differentiate them from materials based on transition metal complexes. The first two chapters discuss the most representative examples of purely organic 3-D magnets as well as the through-space ferromagnetic interactions responsible of the bulk.

Ebook "Iron catalysis II (Topics in Organometallic chemistry, Volume 50)" outlines new avenues for the production of a variety of organic compounds under iron catalysis. Challenges still remain. Iron complexes exhibit a number of features that are not prevalent for other transition metals. Iron is stable in a variety of oxidation states, with +2 and +3 being probably the most prevalent ones for precatalysts.

Ebook "Late transition metal-carboryne complexes: Synthesis, structure, bonding, and reaction with alkenes and alkynes" shows in this thesis that transition metals can mediate or catalyze the cycloaddition or coupling reactions of carboryne with alkynes or alkenes to afford benzocarboranes, alkenylcarboranes or dihydrobenzocarboranes. These results represent powerful strategies to assemble useful complex molecules from very simple precursors in a single operation. Carboranes have many applications in medicine.
