Boron oxide may refer to one of several oxides of boron: Boron trioxide (B 2 O 3, diboron trioxide), the most common form; Boron monoxide (BO) Boron suboxide (B 6 O)
Boron trioxide or diboron trioxide is the oxide of boron with the formula B 2 O 3. It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty.
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.
Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger ...
This unusual structure, which was deduced only in the 1940's, was an early indication of the many surprises provided by boron chemistry. [49] Structure of diborane. Pyrolysis of diborane gives boron hydride clusters, such as pentaborane(9) B 5 H 9 and decaborane B 10 H 14.
Boron suboxide (chemical formula B 6 O) is a solid compound with a structure built of eight icosahedra at the apexes of the rhombohedral unit cell. Each icosahedron is composed of twelve boron atoms. Two oxygen atoms are located in the interstices along the [111] rhombohedral direction.
Structure of a rare monomeric boron hydride, R = i-Pr. [4] The most-studied class of organoboron compounds has the formula BR n H 3−n. These compounds are catalysts, reagents, and synthetic intermediates. The trialkyl and triaryl derivatives feature a trigonal-planar boron center that is typically only weakly Lewis acidic.
When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”. Thus the normal oxide of caesium is Cs 2 O, which is described as a Cs + salt of O 2−. A suboxide of caesium is Cs 11 O 3, where the charge on Cs is clearly less than 1+, but the oxide is still described as O 2−.
