Silicon Di-imide, Si(NH)2
Silicon Di-imide, Si(NH)2, is formed from the tetramide by loss of ammonia:
Si(NH2)4 = Si(NH)2 + 2NH3, which commences above 0° C. and is complete at 120° C. It is also produced by the action of liquid ammonia on silicon disulphide or thio-chloride, and may be isolated from the product of the action of gaseous ammonia on silicon tetrachloride. Silicon di-imide is a white, infusible, amorphous powder, stable towards moderate heat in absence of air; it is basic, forming the white hydrochloride Si(NH)2.2HCl. Water hydrolyses it to silicic acid and ammonia. |
