Abstract:
A series of dinuclear lanthanide complexes incorporating the 2-ethoxycinnamate ligand have been synthesized and characterized using elemental analyses, infra-red spectroscopy, X-ray diffraction and magnetic measurements. Depending on the nature of the lanthanide ion, three different isostructural series of respective formulas, [Ln(L)3(DMSO)(H2O)]2 (Ln = Ce (1), Nd (2)), [Ln(L)3(DMSO)x(DMF)y(H2O)]2 (Ln = Gd (3), Dy (5) and Er (6)) and [Tb(L)3(DMF)(H2O)]2 (4) have been obtained. Investigations of their magnetic properties reveal a genuine single-molecule magnet behaviour observed for the dysprosium based compound 5, while a field-induced slow relaxation of the magnetization is found for compounds 1, 2 and 3.

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
