Ammonium tetrathiovanadate is a chemical compound with the chemical formula (NH4)3VS4.
Physical properties
Ammonium tetrathiovanadate forms violet crystals of orthorhombic symmetry.
Chemical properties
Like other ammonium salts, ammonium tetrathiovanadate decomposes when heated:
- (NH4)3VS4 → 6NH3↑ + 3H2S↑ + V2S5
- V2S5 → V2S3 + 2S
