Boron monoxide (BO) is a binary compound of boron and oxygen. It has a molar mass of 26.81 g/mol. It has a molar mass of 26.81 g/mol. The material was first reported in 1940, [ 1 ] with a modified synthetic procedure published in 1955, [ 2 ] however, the material's structure had remained unknown for nearly a century.
Boron monofluoride monoxide or oxoboryl fluoride [2] or fluoroxoborane is an unstable inorganic molecular substance with formula FBO. It is also called boron fluoride oxide, fluoro(oxo)borane or fluoro-oxoborane. The molecule is stable at high temperatures, but below 1000 °C condenses to a trimer (BOF) 3 called trifluoroboroxin.
The larger boranes all consist of boron clusters that are polyhedral, some of which exist as isomers. For example, isomers of B 20 H 26 are based on the fusion of two 10-atom clusters. The most important boranes are diborane B 2 H 6 and two of its pyrolysis products, pentaborane B 5 H 9 and decaborane B 10 H 14.
The substance can be seen with empirical formula B 12 C 3 (i.e., with B 12 dodecahedra being a motif), but with less carbon, as the suggested C 3 units are replaced with C-B-C chains, and some smaller (B 6) octahedra are present as well (see the boron carbide article for structural analysis). The repeating polymer plus semi-crystalline ...
Atomic structure and electron micrographs of ideal (top) and twinned (bottom) B 6 O. Green spheres are boron, red spheres are oxygen. [8]B 6 O has a strong covalent nature and is easy to compose at temperatures greater than 1,973 K. [7] Boron suboxide has also been reported to exhibit a wide range of superior properties such as high hardness with low density, high mechanical strength ...
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.
BF can react with itself to form polymers of boron containing fluorine with between 10 and 14 boron atoms. BF reacts with BF 3 to form B 2 F 4. BF and B 2 F 4 further combine to form B 3 F 5. B 3 F 5 is unstable above −50 °C and forms B 8 F 12. This substance is a yellow oil. [7] BF reacts with acetylenes to make the 1,4-diboracyclohexadiene ...
The reaction of boron trichloride with alcohols was reported in 1931, and was used to prepare dimethoxyboron chloride, B(OCH 3) 2 Cl. [3] Egon Wiberg and Wilhelm Ruschmann used it to prepare tetrahydroxydiboron by first introducing the boron–boron bond by reduction with sodium and then hydrolysing the resulting tetramethoxydiboron, B 2 (OCH 3) 4, to produce what they termed sub-boric acid.
