Cyanide-bridged polynuclear complexes
The three mixed valent dinuclear cyanide-bridged complexes LMCNFeCl3, (LM = Cp(dppe)Fe, Cp(dppe)Ru and Cp(PPh3)2Ru) were synthesized and characterized by X-ray single crystal determination, IR, UV-Vis and cyclic voltammograms, respectively. The three mixed valent dinuclear complexes display metal- …

Ligand reactivities in platinum and palladium chalcogen complexes
… The high reactivity of d10 metal-metal bonded complexes towards {PtX4} and {Pt2(B5-S)2} core have been demonstrated through the successful isolation of a number of novel homo- and hetero-polynuclear complexes of [Pt2M2(N<3-S)2(N<-dppy)2(dppy)2(N<-dppm)][PF6]2, …

Strategies to Optimize Photophysical Properties in Cyclometalated Iridium Complexes
… growing interest in iridium(III) organometallic complexes for their optoelectronic applications. This thesis delves into the synthesis, structural characterization, and photophysical properties of several new iridium-based complexes. The research is divided into six sections, each contributing to …

Mono- and polynuclear Ferrocenyl-derived complexes: synthesis, characterisation and biological evaluation as antimycobacterial and antiplasmodial agents
… Mononuclear ferrocenyl-derived imino complexes were synthesised by Schiff-base condensation reactions of (E)-4-vinylferrocenylbenzaldehyde with various amines. This included the preparation of a silicon-containing derivative and its carbon analogue, to determine the effect of the …

Coordination chemistry of cis,trans-1,3,5-Triaminocyclohexane : from mononuclear complexes to supramolecular architectures
… CuSO\(_4\)} leads to discrete diligand complexes. Protonation of the copper(II) complexes predominantly forms monoligand species, which can aggregate into higher nuclearity clusters. Protonated Cu(NO\(_3\))\(_2\) and CuBr\(_2\) complexes (HNO\(_3\) and HBr, respectively) remain …

Measurement of hydrolysis, polymerization and complexation in dilute aluminum solutions
… in 1 M, 0.1 M and 0.01 M KCl. A large degree of polynuclear character of Al solutions was found even at Al concentrations as low as 10⁻⁵ M. The n value and size of the polynuclear complexes are affected by Al concentration. The concentration constant, pQ₁₃ is found to be at least 17.4-17.7. It is …

In search for 3d/4f- and 4f-metal complexes with interesting magnetic and/or optical properties
… NiII/LnIII, ZnII/LnIII and LnIII dinuclear and polynuclear complexes with 2-pyridyl oximes and aminoalcohols as primary organic ligands, where LnIIIs are trivalent lanthanides and YIII (which is not a lanthanide). Molecular dinuclear and polynuclear (coordination clusters) lanthanide(III) …

Synthesis and characterisation of small molecule and macromolecular photoredox catalysts for radical thiol-ene reactions
The use of polynuclear complexes is attracting significant attention, offering several advantages over mononuclear analogues. In the context of this project, the presence of several photoactive centres can lead to a multi-electron transfer in a single step and offering other modalities. With the …

Liquid Crystalline Copper(II) Complexes of Poly(propylene imine) Dendrimers
… With this motivation new liquid crystalline, polynuclear complexes of mesogenic 3,4-decyloxybenzoyl-functionalized poly(propylene imine) PPI dendrimers from 1st to 5th generation as ligands and copper(II) as paramagnetic centres have been synthesised. The dendrimeric complexes were prepared by …
