Synthesis and characterization of various coinage metal complexes with bridging diimine ligands
… of coinage metal complexes with various bridging diimine ligands. It has 75pp, 4 tables, 55 figures and the references for the study of group 11 elements. It discusses one main project divided by three chapters describing in general the synthesis; structure and spectroscopic studies of Silver (I) …

Diimine complexes of ruthenium(ii), rhenium(i) and iron(ii): from synthesis to DFT studies
… rhenium(I) tricarbonyl complexes containing the diimine ligands 2,2’-bipyrazine (bpz) and 5,5’-dimethyl-2,2’-bipyrazine (Me2bpz) are discussed. When compared to similar rhenium(I) tricarbonyl complexes of 2,2’-bipyridine (bpy) and 2,2’-bipyrimidine (bpm), the Me2bpz complexes are comparable to …

Synthesis of mixed ligand, water soluble square planar platinum (II) complexes and an investigation of their association with haematin and potential to inhibit the formation of synthetic malaria pigment
… (II) ion coordinated to acylthiourea and diimine ligands. The diimines used included both substituted and unsubstituted 2,2’-bipyridines and 1,10-phenanthrolines. 2-phenyl pyridine was also utilised as a ligand. It has been shown that the uncoordinated planar ligands interact weakly with …

Tetraazamacrocyclic ligands and their copper complexes
… diamines has allowed the isolation of metal-free diimine macrocycles without recourse to metal template' or 'high dilution' techniques. In several cases these diimines were successfully reduced to yield the related tetraamine macrocycles. For the 15-membered macrocycle, …
