Experimental And Theoretical Studies Of Binding Interactions In Divalent Transition Metal Cation-N-Donor Ligand Complexes: Structures, Sequential Bond Dissociation Energies, Mechanisms And Energetics Of Collision-Induced Dissociation
… of the metal cation, the nature and number of ligands, as well as the effects of chelation and steric interactions on the geometry and binding strength of transition metal cation-ligand complexes. The experimental studies make use of energy-resolved collision-induced dissociation (CID) …

Synthesis and chemistry of thione-iron carbonyl complexes
<p>The first examples of sulfur-donor ligand <i>ortho</i>-metallated complexes were obtained in good to excellent yields by reaction of various thiobenzophenones and a thiobenzoate with diiron enneacarbonyl in benzene at room temperature. The known trinuclear complex …

Advancing solvent extraction technology for improved management of contaminated liquors
… and minor actinides with several nitrogen donor ligands which have been developed for the difficult task of AnIII/LnIII separation. A systematic QTAIM study of Ln bond characterisation across the series is reported for one such ligand, bis-triazinyl-pyridine (BTP), confirming the general …

Rational Design of Catalytic Metal Complexes for Potential Applications in Anticancer Chemotherapy
… which afforded an understanding of the optimal donor ligand(s) and structural motif required for both effective catalytic activity in redox-based chemical transformations and long-term stability in strict biologically relevant conditions. Cancer cell death via a redox imbalance can be caused by …

Structural studies of mercuric halide complexes.
… and (L)[2]HgX[2] (where L= neutral unidentate ligand; X=CI,Br or I) have been critically reviewed and indicate that gross assumptions, often invalid, have been made concerning the relationships between crystal structure and vibrational spectra. In an attempt to provide a sound basis from which …

Synthesis of multicomponent heavy alkali metal amide systems and extensions to zirconium chemistry
… in the presence of a multidentate Lewis base donor ligand, taking on different structural guises depending on the denticity of the ligand of choice. This topic is currently a hot topic in organometallic chemistry, being lithium amide congeners have already been characterised. This study allows …

Synthesis, Structure and Spectroscopy of Heteropentadienyl-Cobalt Complexes
A heteropentadienyl ligand is a molecule in which the terminal carbon of a pentadienyl ligand has been replaced with a heteroatom: O, PR, NR, S, SiR2). The study of heteropentadienyl-transition metal complexes has been an active area of research in the last decade, and has recently received …

Synthesis and Electrochemical Properties of {[(bpy)₂Ru(dpp)]₂RhCl₂}(PF₆)₅: A Light Absorber - Electron Collector - Light Absorber Triad AND Development and Evaluation of Integrated Molecular Modeling, Synthesis, and Characterization Laboratory Experiments for the Undergraduate Chemistry Curriculum
… a RhI complex that had lost two chloride ligands: {[(bpy)2Ru(dpp)]2RhI}+5. In the absence of sufficient water, two-electron reduction yields a breakdown of the trimetallic resulting in [(bpy)2Ru(dpp)]+2 and {[(bpy)2Ru(dpp)]RhICl₂}+. The second research goal was to develop integrated …

1,2–Dithiolate Complexes of the Lanthanides and Actinides and High– Pressure Studies of f–Element Complexes
… can be increased by complexation with soft–donor ligands which increase orbital overlap and covalent bonding with actinide complexes in comparison to lanthanide complexes, leading to shorter bond distances and structural differences. Differences in lanthanide and actinide bonding can also be …

Spectroscopic and functional models for Hmd hydrogenase
… on Hmd revealed the presence of iron, carbonyl ligands, and a 2-pyridinol-6-acetic acid derivative. We examined the metal coordination of a similar ligand, 4-methyl-2-hydroxypyridine-6-acetic acid (cmhpH2), on the simplified platforms of Cp*Ir and Cp*Rh. We were able to show the cmhpH ligand …

Investigations into cyclopropanation and ethylene polymerization via salicylaldiminato copper (II) complexes
… little relates the two chapters apart from the ligands. The first chapter addresses diastereoselective homogeneous copper catalyzed cyclopropanation reactions. Cyclopropanation of styrene and ethyl diazoacetate (EDA) is a standard test reaction for homogeneous catalysts. Sterically bulky …
