Experimental iron-silicon phase diagram. Binary compounds of silicon are binary chemical compounds containing silicon and one other chemical element. [1] Technically the term silicide is reserved for any compounds containing silicon bonded to a more electropositive element.
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds.

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.
