I’m sorry, but SiH2N is not the correct chemical formula for any compound. You might be confusing it with another compound.
However, if you’re interested in the compounds of silicon and nitrogen, you might want to look into silazanes (with a general formula of (SiH2NH)n) or silanes (with a general formula of (SiH4)n). Both are types of compounds of silicon, hydrogen and nitrogen, used in many technological applications such as polymer production and semiconductor materials.
If you want to learn about the structure and properties of a specific compound, make sure that you provide the correct chemical formula for it.
