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
