Silane (Silicane) is an inorganic compound with chemical formula SiH 4.It is a colorless, pyrophoric, toxic gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid. [5]
Chemical structure of disilane, which is structurally similar to ethane. Silanes are saturated chemical compounds with the empirical formula Si x H y. They are hydrosilanes, a class of compounds that includes compounds with Si−H and other Si−X bonds. All contain tetrahedral silicon and terminal hydrides. They only have Si−H and Si−Si ...
In this type of reaction, carbocations are generated by the action of strong Lewis or Brønsted acids in the presence of hydrosilanes, which then transfer hydride. A typical acid is trifluoroacetic acid (TFA). The reaction is stoichiometric.
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. Binary silicon compounds can be grouped into several classes.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F 4.This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
The ordered structure forms the β- phase, whereas the higher temperature and more symmetrical disordered structure is called α- phase. The β- phase is about 15% more compact than the α-phase. [8] The silanide ion has C 3v symmetry. The silicon to hydrogen bond length is 1.52 Å and the H-Si-H bond angle is 92.2°, not far off a right angle. [8]
Representative d-orbital splitting diagrams for square planar complexes featuring σ-donor (left) and σ+π-donor (right) ligands. A general d-orbital splitting diagram for square planar (D 4h) transition metal complexes can be derived from the general octahedral (O h) splitting diagram, in which the d z 2 and the d x 2 −y 2 orbitals are degenerate and higher in energy than the degenerate ...
