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.
In the picture below the caesium atoms are purple and the oxygen atoms are red. The Cs-Cs distance in the cluster is 376 pm, which is less than the Cs-Cs distance in the metal of 576 pm. Rb 9 O 2 and Rb 6 O both contain the Rb 9 O 2 cluster, which can be visualised as two face-sharing octahedra. Rb 6 O can be formulated as (Rb 9 O 2)Rb 3. The ...
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 .
Although the Sun is a star, its photosphere has a low enough temperature of 6,000 K (5,730 °C; 10,340 °F), and therefore molecules can form. Water has been found on the Sun, and there is evidence of H 2 in white dwarf stellar atmospheres.
A reported silicon phosphide is Si 12 P 5 (no practical applications), [89] [90] formed by annealing an amorphous Si-P alloy. The arsenic–silicon phase diagram measured at 40 Bar has two phases: SiAs and SiAs 2. [91] The antimony–silicon system comprises a single eutectic close to the melting point of Sb. [92] The bismuth system is a ...
Examples of molecular oxides are carbon dioxide and carbon monoxide. All simple oxides of nitrogen are molecular, e.g., NO , N 2 O , NO 2 and N 2 O 4 . Phosphorus pentoxide is a more complex molecular oxide with a deceptive name, the real formula being P 4 O 10 .

VO is a non-stoichiometric compound, its composition varying from VO 0.8 to VO 1.3. [2] Diatomic VO is one of the molecules found in the spectrum of relatively cool M-type stars. [3] A potential use of vanadium(II) monoxide is as a molecular vapor in synthetic chemical reagents in low-temperature matrices. [4]
