Lithium metaborate is a chemical compound of lithium, boron, and oxygen with elemental formula LiBO 2. It is often encountered as a hydrate , LiBO 2 · n H 2 O , where n is usually 2 or 4. However, these formulas do not describe the actual structure of the solids.
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
The structure of the perborate ion ([B 2 O 4 (OH) 4] 2−). This anion is a cyclic molecule and has a tetrahedral molecular geometry at the boron atoms. It contains two bridging peroxide groups (−O−O−) and four hydroxyl groups (−OH) attached to boron atoms, two per each boron. The ring has a chair conformation. [4]
Lithium borate [1], also known as lithium tetraborate [2], dilithium tetraborate [3] or boron lithium oxide [2] is an inorganic compound with the formula Li 2 B 4 O 7. A colorless solid, lithium borate is used in making glasses and ceramics. It is not to be confused with B 8 Li 2 O 13, also called lithium borate. [4]
The anion is tetrahedral with B-C bond lengths of approximately 1.65 Angstroms. The salt has only been obtained as the etherate, and the crystallography confirms that four ether (OEt 2) molecules are bound to the lithium cation, with Li-O bond lengths of approximately 1.95 Å.
A metaborate is a borate anion consisting of boron and oxygen, with empirical formula BO − 2.Metaborate also refers to any salt or ester of such anion (e.g. salts such as sodium metaborate NaBO 2 or calcium metaborate Ca(BO 2) 2, and esters such as methyl metaborate CH 3 BO 2).
Boron-boron multiple bonds are rare, although doubly-bonded dianions have been known since the 1990s. [20] Neutral analogues use NHC adducts, such as the following diborane(2) derivative: [21] [22] Each boron atom has an attached proton and is coordinated to a NHC carbene. [23] [24] A reported diboryne is based on similar chemistry. [25]
Lithium tetrafluoroborate is an inorganic compound with the formula Li BF 4. It is a white crystalline powder. It is a white crystalline powder. It has been extensively tested for use in commercial secondary batteries, an application that exploits its high solubility in nonpolar solvents.
