Zinc enzyme model complexes with Ligands containing a N2S Donor Set and their methylating reactions
… and two new tripodal ligands containing a N2S donor set have <br>been prepared in this work. These and other four selected ligands together with <br>different thiolate co-ligands have been used for the syntheses of 47 new zinc <br>enzyme model complexes. These complexes have been characterized …

Chemistry and biology of tricarbonyl complexes of technetium and rhenium
… center in a tridentate fashion utilizing an 000 donor set. The ligands LOR can be used as models for facially coordinated triaqua groups owing to their position in the spectrochemical series. Therefore, these four compounds, M(CO)3(LoR), can be considered structural models for [M(H2O)3(CO)3]+. …

Synthesis and characterization of ruthenium complexes with (N-N)(P-P) and (N-P)2 donor sets
… sphere of the metal centers. In this work, the donor sets of the ruthenium complexes were modified from the most investigated (P-P)(P-P) to (N-N)(P-P) and (N-P)2 and a series of ruthenium complexes were synthesized and characterized. In Chapter 2, the study of the Ru(N-N)(P-P) complexes is …

Synthesis and complexes of new selenoether macrocycles
… novel macrocycles containing a mixed O/Se donor set of the type OxSe2x, two small ring Se3 macrocycles and two Se2N macrocycles have been synthesised. Two methods of production have been investigated from the same precursors, a NaBH4 reduction and a low temperature Na/NH3 (l) reduction, …

I The synthesis and coordination chemistry of novel 1,1,1-tris(aminomethyl)ethane (TAME) derived ligands and their use as size selective fluorescent zinc(II) sensors II The synthesis of strongly and weakly binding ligands with nitrogen, oxygen, and sulfur-donor groups to be used as receptors in fluorescent ratiometric indicators for transition metal ions
… to the target analyte from the polydentate N6-donor set was evidenced in the measured K d' of 1.4 fM for [Zn(TAMEisoquin)]2+. Unlike many reported sensors, the TAME-based chelators display excellent selectivity for Zn(II) over Cd(II). Moreover, the synthetic flexibility of the TAME podand for …
