Manganese heptoxide with sulfuric acid to give the remarkable manganyl(VII) cation , which is isoelectronic with CrO MnO decomposes near room temperature, explosively so above 55 °C. The explosion can be initiated by striking the sample or by its exposure to oxidizable organic compounds. The products are MnO and O. Ozone is also produced, giving a strong smell to the substance.
