Chemical compound
Indium(II) chloride is an
inorganic compound, an indium metal salt and
hydrochloric acid with the formula InCl2.
[1]
[2]
[3] The compound forms colorless crystals, reacts with water.
[4] This is one of three known
indium chlorides.
Synthesis
Indium(II) chloride can be produced via the effect of dry
hydrogen chloride on indium metal at 2000 °C:
- In + 2HCl → InCl2 + H2
Physical properties
Indium(II) chloride forms colorless diffuse crystals of rhombic shape, lattice cell parameters a = 0.964 nm, b = 1.054 nm, c = 0.685 nm, Z = 8.
The molecules are dimers and have a structure In[InCl4.
Chemical properties
Indium(II) chloride reacts with water.
[5]
-
Water catalyzes a disproportionation reaction:
- 3InCl2 → 2InCl3 + In
- 2InCl2 → InCl3 + InCl
Indium(II) chloride reacts with oxygen in the air when heated:
- 4InCl2 + O2 → 2InOCl + 2InCl3
