slightly soluble in CS₂. Upon heating, it softens at 50 °C and converts to gray selenium at 180 °C; the transformation temperature is reduced by presence of halogens and amines.

The red ?, ?, and ? forms are produced from solutions of black selenium by varying the evaporation rate of the solvent (usually CS₂). They all have a relatively low, monoclinic crystal symmetry
