Synthesis and Characterization of f-Block Quinolate Complexes: a thesis submitted to University of Manchester for the degree of Doctor of Philosophy in the Faculty of Engineering and Physical science submitted March 2019. Novel lanthanide compounds with three different 8-hydroxyquinoline derivatives incorporated in the syntheses are reported. The compounds have been prepared and characterized by elemental analysis, IR spectroscopy and X-ray crystallography and some of them have been investigated by magnetic and EPR measurements. The introduction to this thesis covers some of the important properties of lanthanide metal ions such as, their optical and magnetic properties and their role in the field of single molecular magnetism. In Chapter 2, five complexes with 2-methyl-8-hydroxyquinolino ligands are reported and characterised by elemental analysis, and X-ray crystallography, IR, and EPR spectroscopy and magnetometry. In Chapter 3, novel monometallic lanthanide compounds with 5,7-dimethylhydroxyquinoline [Ln(NdiMeQ)2(H2O)Cl3] (Ln = Pr, Eu, Gd, Tb, Dy, Ho, Er, Yb and Y) are reported and characterised by X-ray crystallography, IR, spectroscopy and some primary magnetic measurements. In Chapter 4, four different 8-hydroxyquinoline derivatives and seven novel trimetallic compounds of lanthanides with 5-ethoxymethyl-8-quinolinol (HEtOQ) where Ln = Gd, Tb, Dy, Ho, Er, Yb and Y are reported. These compounds are characterised by X-ray crystallography, IR spectroscopy and magnetometry. In Chapter 5, three novel monometallic lanthanide complexes with formula [Ln(NdiMeQ)2(MeOH)Cl3], where LnIII = Ho, Tm, Y, HdiMeQ is 5,7-dimethyl-8-hydroxyquinoline protonated at N, are reported, and characterised by X-ray crystallography and IR spectroscopy. In Chapter 6, 5,7-dimethyl-8-hydroxyquinoline (HdiMeQ) was used with lanthanide nitrate (Ln (NO3)3.nH2O) where LnIII = Gd, Tb, Dy, Ho, Er, Yb and Y, but few of them gave crystals suitable for X-ray diffraction. The crystal data for Ln = Dy, Ho, Yb, and Y complexes were collected.
