Vanadium(V) chloride is the inorganic compound with the formula VCl5. It is a black diamagnetic solid. The molecules adopt a bioctahedral structure similar to that of niobium(V) chloride. [1]

Preparation and reactions

Vanadium(V) chloride is prepared from the vanadium pentafluoride with excess boron trichloride:

2 VF5 + 10 BCl3 → [VCl5]2 + 10 BF2Cl

It is unstable at room temperature with respect to vanadium(IV) chloride:

[VCl5]2 → 2 VCl4 + Cl2

In contrast, the heavier analogues NbCl5 and TaCl5 are stable and not particularly oxidizing.

Hydrogen bromide is the inorganic compound with the formula HBr. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. Aqueous solutions that are 47.6% HBr by mass form a constant-boiling azeotrope mixture that boils at 124.3 °C. Boiling less concentrated solutions releases H2O until the constant-boiling mixture composition is reached.

Titanium(II) chloride is the chemical compound with the formula TiCl2. The black solid has been studied only moderately, probably because of its high reactivity. Ti(II) is a strong reducing agent: it has a high affinity for oxygen and reacts irreversibly with water to produce H2. The usual preparation is the thermal disproportionation of TiCl3 at 500 °C. The reaction is driven by the loss of volatile TiCl4:
