Silicon monoxide is the chemical compound with the formula SiO where silicon is present in the oxidation state +2. In the vapour phase, it is a diatomic molecule. [1] It has been detected in stellar objects [2] and has been described as the most common oxide of silicon in the universe.
A silicon–oxygen bond (Si−O bond) is a chemical bond between silicon and oxygen atoms that can be found in many inorganic and organic compounds. [1] In a silicon–oxygen bond, electrons are shared unequally between the two atoms , with oxygen taking the larger share due to its greater electronegativity .
Silicon oxide may refer to either of the following: Silicon dioxide or quartz, SiO 2 , very well characterized Silicon monoxide , SiO, not very well characterized
The silanes comprise a homologous series of silicon hydrides with a general formula of Si n H 2n + 2. They are all strong reducing agents. Unbranched and branched chains are known up to n=8, and the cycles Si 5 H 10 and Si 6 H 12 are also known. The first two, silane and disilane, are colourless gases; the heavier members of the series are ...
Other binary silicon nitrogen compounds have been proposed (SiN, Si 2 N 3, Si 3 N) [86] and other SiN compounds have been investigated at cryogenic temperatures (SiN 2, Si(N 2) 2, SiNNSi). [87] Silicon tetraazide is an unstable compound that easily detonates.
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−. Suboxides typically feature extensive bonding between the electropositive element, often leading to clusters. Examples of suboxides other than alkali metal derivatives: [2] Carbon suboxide, C 3 O 2; Boron suboxide, B 6 O;
The monoxide, germanous oxide, can be obtained by the high temperature reaction of GeO 2 with Ge metal. [4] The dioxide (and the related oxides and germanates) exhibits the unusual property of having a high refractive index for visible light, but transparency to infrared light. [6] [7] Bismuth germanate, Bi 4 Ge 3 O 12, (BGO) is used as a ...
Cerium oxide adopts the fluorite structure, space group Fm3m, #225 containing 8-coordinate Ce 4+ and 4-coordinate O 2−. At high temperatures it releases oxygen to give a non-stoichiometric, anion deficient form that retains the fluorite lattice. [6] This material has the formula CeO (2−x), where 0 < x < 0.28. [7]
