There are some physical property differences between tetrabromotungsten (WBr4) and dibromotungsten (WBr2). The following are their main differences:
Phase: Tungsten tetrabromide is solid at room temperature, and tungsten dibromide is also solid.
Melting point: The melting point of tetrabromotungsten is higher, about 220-230°C. The melting point of tungsten dibromide is lower, about 150-160°C. The melting point of tetrabromotungsten is higher, about 2,000-1,000°C.
Density: The density of tetrabromotungsten is higher, about 7.6-7.7 g/cm³. And the density of tungsten dibromide is lower, about 6.3-6.5 g/cm³.
Color: Tungsten tetrabromide is usually dark brown or reddish brown, while tungsten dibromide is grayish black.
Conductivity: Due to the high electron affinity of the tungsten element in it, both tetra- and dibromotungsten have a certain degree of electrical conductivity, but the specific conductive properties may differ.
The difference in these physical properties mainly stems from factors such as the different coordination modes of tungsten and bromine atoms in the compounds, the crystal structures and the corresponding molecular weights.
