Iridium tetrabromide is a binary inorganic chemical compound of iridium and bromine with the chemical formula IrBr
4.[1][2][3] This is a salt of iridium metal and hydrobromic acid.
Synthesis
Synthesis of iridium tetrabromide can be by solution of iridium(IV) oxide in hydrobromic acid:
- IrO
2 + 4HBr → IrBr
4 + 2H
2O
- IrO
Physical properties
Iridium tetrabromide compound forms black crystals, soluble in water and alcohol.[4][5]
Chemical properties
