The Na 2 SiH 2 dissolves in the mercury to generate the diradical SiH 2, which then forms the final products. [3] Polysilicon hydrides may also be produced by the dehalogenation of polysilicon halides. An illustrative reaction is the debromination of HSiBr 3 with Mg in ether: [4] HSiBr 3 + 3/2 Mg → 1/x (SiH) x + 3/2 MgBr 2
hexasilane Si 6 H 14 or H 3 Si−SiH 2 −SiH 2 −SiH 2 −SiH 2 −SiH 3, 6 silicon atoms and 14 hydrogen atoms, analogous to hexane; Silanes are named by adding the suffix-silane to the appropriate numerical multiplier prefix. Hence, disilane, Si 2 H 6; trisilane Si 3 H 8; tetrasilane Si 4 H 10; pentasilane Si 5 H 12; etc.
The silanide ion has an effective ionic radius of 2.26 Å. In salts at room temperature the ion's orientation is not stable, and it rotates. But at lower temperatures (under 200K) silanide becomes fixed in orientation. [7]
These hydrides decompose to SiH when heated to 750 K. [2] Other ways to coat a silicon surface in hydrogen is via reaction with atomic hydrogen, or hot silane. [3] A (111) crystal face will become covered in the pure monohydride, but other faces on a silicon crystal will also have the dihydride and trihydride groups.
The parent hydrosilane is silane (SiH 4). Commonly, hydrosilane refers to organosilicon derivatives. Examples include phenylsilane (PhSiH 3) and triethoxysilane ((C 2 H 5 O) 3 SiH). Polymers and oligomers terminated with hydrosilanes are resins that are used to make useful materials like caulks.

The SIE format is an open standard for transferring accounting data between different software produced by different software suppliers.. SIE could be used to transfer data between software on the same computer, but also used for sending data between companies, for example between the company, the accountant and the audit.
SiH 3 Br + 2 Me 2 NH → SiH 3 NMe 2 + Me 2 NH 2 Br 4 SiH 3 I + 5 N 2 H 4 → (SiH 3) 2 NN(SiH 3) 2 + 4 N 2 H 5 I. Many such compounds have been prepared, the only known restriction being that the nitrogen is always tertiary, and species containing the SiH–NH group are unstable at room temperature. The stoichiometry around the nitrogen atom ...
