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.
Silicon–oxygen single bonds are longer (1.6 vs 1.4 Å) but stronger (452 vs. about 360 kJ mol −1) than carbon–oxygen single bonds. [1] However, silicon–oxygen double bonds are weaker than carbon–oxygen double bonds (590 vs. 715 kJ mol −1) due to a better overlap of p orbitals forming a stronger pi bond in the latter. This is an ...

2) or four silicon atoms (e.g. [K +] 4 [Si 4] 4−) at first, followed by chains (e.g. CaSi), layers (e.g. CaSi 2), or three-dimensional networks of silicon atoms spanning space (e.g. α-ThSi 2) as the silicon content rises even higher. [2] The silicides of the group 1 and 2 metals usually are more reactive than the transition metal silicides.
