Research on magnetic properties of lanthanoid complexes has led to group of complexes that show slow relaxation of magnetization of purely molecular origin in low temperatures. Such complexes are called lanthanoid single molecular magnets (Ln-SMM). Recently, lanthanoids have dominated the development of new SMMs over the transition metals. Anisotropy of lanthanoid ion and the ligand field geometry around the ion are the main things affecting on the magnetic properties of the complex. Most successful metal-ligand combination in the field of Ln-SMMs has been dysprosium metallocenium unit [(C5R5)2Dy]n+. This thesis gives a short introduction to the magnetic capabilities and synthetic matters of lanthanoid complexes based on cyclopentadienyl ligands. \n\nThis thesis consists of the literature part and experimental part. First in the literature part basic concepts and theory about lanthanoids, cyclopentadienyls and single molecular magnetism are presented shortly. Then mononuclear complexes will be discussed starting from the development and potential of divalent lanthanoid ions (M2+) in the complexes of cyclopentadienyl ligands. Trivalent lanthanoid ions (M3+) in the mononuclear cyclopentadienyl complexes are also dealt with before discussing the polynuclear complexes, which are divided in two groups. The first group includes complexes with bridging ligands that have heteroatoms as donor atoms, whereas the second group focuses the hydride bridged complexes. The main emphasis is on the latest achievements in each field, but development of the complexes is also discussed.\n \nIn the experimental part, the syntheses and reductions of dinuclear rare-earth metal complexes with the redox active bridging ligand are discussed. Due to the results of experimental part will be published in the peer-reviewed scientific journal, they will be published in JYX after they are accepted for the publication because of prior publication policies of scientific journals.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-05-15T08:15:00Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-05-15T08:15:00Z (GMT).
