2. Synthesis and Structural Characterization of Copper(I) Complexes with Hard Donor Ligands
Abstract : Syntheses and crystal structures of nine new copper(I) complexes and one novel mixed-valence copper(I/II) complex are reported: two homoleptic phenoxides and eight complexes with N-donor ligands. The copper(I) and the copper(I/II) phenoxide complexes have been prepared by reactions between mesitylcopper(I) and 2-allyl-6-methylphenol in toluene. READ MORE

3. A nuclear magnetic resonance study of dialkyldithiophosphate complexes : polycrystalline and surface adsorbed
Abstract : 31P, 13C and 207Pb NMR were used to characterize different metal (Ni, Zn, Pb) dialkyldithiophosphate complexes. Eight different sodium or potassium dialkyldithiophosphate salts (alkyl groups R=ethyl-, n-propyl, iso-propyl, n- butyl, iso-butyl, sec-butyl, iso-amyl and cyclo-hexyl) were used as starting materials.

4. Dinuclear metal complexes modelling active sites of metallohydrolases
Abstract : To study the active sites of dinuclear metallohydrolases new metal complexes that model these sites both in structure and function have been synthesized using two new phenol based dinucleating ligands, 2-(N-isopropyl-N-((2-pyridyl)methyl)aminomethyl)-6-(N-(carboxylmethyl)-N-((2-pyridyl)methyl)aminomethyl)-4-methylphenol (IPCPMP) and 2,6-Bis[N-(N-(carboxymethyl)-N-(pyridylmethyl)amine)methyl]-4-methylphenolate (BCPMP). Both ligands contain pyridyl, tertiary amine and carboxylate groups but in IPCPMP one carboxylate donor is exchanged for a non-coordinating group yielding an unsymmetric ligand while BCPMP is symmetric with identical sets of ligands on either side of the phenol group.

5. Mechanistic Studies of Dinuclear Metalloenzymes - A Model Approach
Abstract : With the goal to study the mechanisms of dinuclear metalloenzymes, a new line of synthetic and computational models were prepared and studied. Mixed imidazole and carboxylate multidentate complexes were synthesized to better simulate carboxylate-rich ligand environments. READ MORE
