Dichlororuthenium tricarbonyl dimer is an organoruthenium compound with the formula [RuCl2(CO)3]2. A yellow solid, the molecule features a pair of octahedral Ru centers bridged by a pair of chloride ligands. The complex is a common starting material in ruthenium chemistry. [1]

Synthesis and reactions

Dichlororuthenium tricarbonyl dimer arises by the carbonylation of a hot solution of ruthenium trichloride in methoxyethanol. [2]

The complex exists in equilibrium with the polymer:

n [RuCl2(CO)3]2 → [RuCl2(CO)2]2n + 2 CO

It reacts with potassium hydroxide in alcohol to give triruthenium dodecacarbonyl.

Dichlororuthenium tricarbonyl dimer reacts with glycine to give tricarbonylchloroglycinatoruthenium(II). [3]

<span class="mw-page-title-main">Electrochemiluminescence</span> Emission of light from electrochemical reactions

Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state. This wavelength of the emitted photon of light corresponds to the energy gap between these two states. ECL excitation can be caused by energetic electron transfer (redox) reactions of electrogenerated species. Such luminescence excitation is a form of chemiluminescence where one/all reactants are produced electrochemically on the electrodes.

DNA-binding metallo-intercalators are positively charged, planar, polycyclic, aromatic compounds that unwind the DNA double helix and insert themselves between DNA base pairs. Metallo-intercalators insert themselves between two intact base pairs without expelling or replacing the original nitrogenous bases; the hydrogen bonds between the nitrogenous bases at the site of intercalation remain unbroken. In addition to π-stacking between the aromatic regions of the intercalator and the nitrogenous bases of DNA, intercalation is stabilized by van der Waals, hydrophobic, electrostatic, and entropic interactions. This ability to bind to specific DNA base pairs allows for potential therapeutic applications of metallo-intercalators.

Photo-Induced Cross-Linking of Unmodified Proteins (PICUP) is a protein cross-linking method by visible light irradiation of a photocatalyst in the presence of an electron acceptor and the protein of interest. Irradiation results in a highly reactive protein radical that forms a covalent bond between the amino acid side chains of the proteins to be linked. Cross-linking methods developed prior to PICUP, including the use of physical, oxidative, and chemical cross-linkers, often require more time and result in protein byproducts. In addition, the cross-linked protein yield is very low due to the multifunctionality of the cross-linking reagents.

Transition metal complexes of 2,2'-bipyridine are coordination complexes containing one or more 2,2'-bipyridine ligands. Complexes have been described for all of the transition metals. Although few have any practical value, these complexes have been influential. 2,2'-Bipyridine is classified as a diimine ligand. Unlike the structures of pyridine complexes, the two rings in bipy are coplanar, which facilitates electron delocalization. As a consequence of this delocalization, bipy complexes often exhibit distinctive optical and redox properties.
