Co-condensation of lanthanide metals with 1,3-butadiene (1,3-C4H6) or 2,3-dimethyl-1,3-butadiene (2,3-(CH3)2-1,3-C4H4) produces three types of organolanthanide complexes differentiated by their solubility in pentane, toluene and tetrahydrofuran (THF). The THF soluble species are formed in highest yield and have been most completely characterized. Elemental analysis shows that when butadiene is the ligand, complexes of empirical formula Ln(C4H6)3 (Ln = Nd, Sm, Er) are obtained. When dimethylbutadiene is used, Ln((CH3)2C4H4)2 is obtained (Ln = La, Nd, Sm, Er). These compounds differ from all other organolanthanide complexes in several respects. First, it is unusual to be able to obtain such good analytical data. Generally, for organolanthanides, incomplete carbon and hydrogen combustion is observed. Second, the stoichiometries are difficult to reconcile with known lanthanide chemistry. If the dienes coordinate as .pi.-ligands, the metals are formally zero-valent. If the dienes coordinate as dialkyl-2-butene moieties, the metals must be in the +6 oxidation state in the butadiene series and the +4 oxidation state in the dimethylbutadiene series. The physical properties of these new complexes are also unusual. The sharp, line-like, 4f-4f optical transitions normally observed for lanthanide complexes are not observed in the visible and near infrared regions. Instead a single broad band dominates the spectrum. The room temperature magnetic moments are similarly not consistent with known Ln/sup 3 +/ species. Most unusual in this respect is the lanthanum complex, which is the first paramagnetic organolanthanum complex ever observed. Further investigations of diene reactions with lanthanides in chemical reduction syntheses are summarized. (JRD).

Book excerpt: Investigations are being conducted on two classes of lanthanide compounds: metal vapor co-condensation reactions with unsaturated hydrocarbons and homoleptic and heteroleptic alkyl lanthanide complexes. Three models have been considered for the interaction of erbium atoms with 3-hexyne. The structure of the heteroleptic alkynide ((C5H5)2ErC triple bond CCMe3)2 was studied. Some new organolanthanides have been prepared. (DLC).

Available in PDF, EPUB and Kindle. Book excerpt: The only introduction into the exciting chemistry of Lanthanides and Actinides. The book is based on a number of courses on "f elements" The author has a long experience in teaching this field of chemistry Lanthanides have become very common elements in research and technology applications; this book offers the basic knowledge The book offers insights into a vast range of applications, from lasers to synthesis The Inorganic Chemistry: A Textbook series reflects the pivotal role of modern inorganic and physical chemistry in a whole range of emerging areas, such as materials chemistry, green chemistry and bioinorganic chemistry, as well as providing a solid grounding in established areas such as solid state chemistry, coordination chemistry, main group chemistry and physical inorganic chemistry. Lanthanide and Actinide Chemistry is a one-volume account of the Lanthanides (including scandium and yttrium), the Actinides and the Transactinide elements, intended as an introductory treatment for undergraduate and postgraduate students. The principal features of these elements are set out in detail, enabling clear comparison and contrast with the Transition Elements and Main Group metals. The book covers the extraction of the elements from their ores and their purification, as well as the synthesis of the man-made elements; the properties of the elements and principal binary compounds; detailed accounts of their coordination chemistry and organometallic chemistry, from both preparative and structural viewpoints, with a clear explanation of the factors responsible for the adoption of particular coordination numbers; spectroscopy and magnetism, especially for the lanthanides, with case studies and accounts of applications in areas like magnetic resonance imaging, lasers and luminescence; nuclear separations and problems in waste disposal for the radioactive elements, particularly in the context of plutonium. Latest developments are covered in areas like the synthesis of the latest man-made elements, whilst there is a whole chapter on the application of lanthanide compounds in synthetic organic chemistry. End-of-chapter questions suitable for tutorial discussions are provided, whilst there is a very comprehensive bibliography providing ready access to further reading on all topics.

This book was released on 2007-12-31 with total page 4059 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.
