Is it possible to be synthesis?

[Heleon]

Al+Si+P+S= 📖

[ChenBeier]

You can combine them. What you want ro produce.

[Heleon]

4-element compound

[Heleon]

\(\mathbf{Al(SiPS)}_3\) or \(\mathbf{AlSiPS_2}\)?

[ChenBeier]

Aluminium is 3 valent, silicon 4 valent phosphorous 3 valent and 2 sulfur valent. So your compounds not possible.

[Heleon]

Aluminium is 3 valent, silicon 4 valent phosphorous 3 valent and 2 sulfur valent. So your compounds not possible.

+3 +4 -3 -2
Al ( Si P S ) 3
+4-3-2=-1, -1*3=-3, +3-3=0. should be possible
+3 +4 -3 -2
Al Si P S₂
+3+4=+7, -3-2*2=-7, +7-7=0. possible

[ChenBeier]

The first one would be 3 times [S-Si=P]- and Al 3+
Theoretical possible. Aluminium thio phosphino-silicate.
Second one is only mathematical, it guides to two compounds Aluminiumphoshide AlP and silicon disulfide SiS₂
Al 3+ And P 3- and Si 4+ and 2 times S 2-.
