Mercury(II) sulfide has several modifications, the only two stable allotropic forms are:<br /> 1. the red hexagonal form known as cinnabar (alpha form), and 2. the black cubic modification (beta form).<br /> Cinnabar is a red crystalline or powdery substance; hexagonal crystal system; refractive index 2.854; density 8.10 g/cm3; sublimes at 583.5&deg;C; color changes to brown at 250&deg;C and converts to black sulfide at 386&deg;C; reverts to red color on cooling; insoluble in water, alcohol and nitric acid; soluble in aqua regia and solutions of alkali metal sulfides; decomposed by hot concentrated sulfuric acid.<br /> Black sulfide is a black amorphous powder or crystalline substance (beta form); cubic structure; metastable at ordinary temperatures; converts to red sulfide by sublimation at ordinary pressure; density 7.73 g/cm3; melts at 583.5&deg;C; insoluble in water, alcohol and nitric acid; soluble in aqua regia, alkalies, and solutions of alkali metal sulfides.
