Rhenium(VI) chloride is the inorganic compound with the formula ReCl6. It is a black paramagnetic solid. The molecules adopt an octahedral structure as seen in tungsten(VI) chloride. [1]

Preparation and reactions

Rhenium(VI) chloride was first generated as a mixture by chlorination of Re films. [2] Bulk samples can be prepared by combining rhenium hexafluoride with excess boron trichloride:

2 ReF6 + 6 BCl3 → ReCl6 + 6 BF2Cl

It is unstable at room temperature with respect to rhenium(V) chloride:

2 ReCl6 → [ReCl5]2 + Cl2

Rhenium Chemical element with atomic number 75

Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. Rhenium has the third-highest melting point and second-highest boiling point of any stable element at 5903 K. Rhenium resembles manganese and technetium chemically and is mainly obtained as a by-product of the extraction and refinement of molybdenum and copper ores. Rhenium shows in its compounds a wide variety of oxidation states ranging from −1 to +7.

Tryptophan repressor Transcription factor

Tryptophan repressor is a transcription factor involved in controlling amino acid metabolism. It has been best forstudied in Escherichia coli, where it is a dimeric protein that regulates transcription of the 5 genes in the tryptophan operon. When the amino acid tryptophan is plentiful in the cell, it binds to the protein, which causes a conformational change in the protein. The repressor complex then binds to its operator sequence in the genes it regulates, shutting off the genes.

Ruthenium(III) chloride

Ruthenium(III) chloride is the chemical compound with the formula RuCl3. "Ruthenium(III) chloride" more commonly refers to the hydrate RuCl3·xH2O. Both the anhydrous and hydrated species are dark brown or black solids. The hydrate, with a varying proportion of water of crystallization, often approximating to a trihydrate, is a commonly used starting material in ruthenium chemistry. The compound is also widely regarded as a prime candidate to realize Kitaev quantum spin liquid state with Majorana Fermion excitations.

Tungsten hexachloride is the chemical compound of tungsten and chlorine with the formula WCl6. This dark violet blue species exists as a volatile solid under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. Other examples of charge-neutral hexachlorides are ReCl6 and MoCl6. The highly volatile WF6 is also known.

Technetium hexafluoride

Technetium hexafluoride or technetium(VI) fluoride (TcF6) is a yellow inorganic compound with a low melting point. It was first identified in 1961. In this compound, technetium has an oxidation state of +6, the highest oxidation state found in the technetium halides. The other such compound is technetium(VI) chloride, TcCl6. In this respect, technetium differs from rhenium, which forms a heptafluoride, ReF7. Technetium hexafluoride occurs as an impurity in uranium hexafluoride, as technetium is a fission product of uranium.

Uranium hexachloride

Uranium hexachloride (UCl6) is an inorganic chemical compound of uranium in the +6 oxidation state. UCl6 is a metal halide composed of uranium and chlorine. It is a multi-luminescent dark green crystalline solid with a vapor pressure between 1-3 mmHg at 373.15 K. UCl6 is stable in a vacuum, dry air, nitrogen and helium at room temperature. It is soluble in carbon tetrachloride (CCl4). Compared to the other uranium halides, little is known about UCl6.

Calcium-dependent chloride channel

The Calcium-Dependent Chloride Channel (Ca-ClC) proteins (or calcium-activated chloride channels, are heterogeneous groups of ligand-gated ion channels for chloride that have been identified in many epithelial and endothelial cell types as well as in smooth muscle cells. They include proteins from several structurally different families: chloride channel accessory, bestrophin, and calcium-dependent chloride channel anoctamin channels]] ANO1 is highly expressed in human gastrointestinal interstitial cells of Cajal, which are proteins which serve as intestinal pacemakers for peristalsis. In addition to their role as chloride channels some CLCA proteins function as adhesion molecules and may also have roles as tumour suppressors. These eukaryotic proteins are "required for normal electrolyte and fluid secretion, olfactory perception, and neuronal and smooth muscle excitability" in animals. Members of the Ca-CIC family are generally 600 to 1000 amino acyl residues in length and exhibit 7 to 10 transmembrane segments.
