Manganese heptoxide

It is a highly reactive and powerful oxidizer that reacts explosively with nearly any organic compound.

Focusing on comparisons within the transition metal series, Tc2O7 and Mn2O7 are structurally similar but the Tc−O−Tc angle is 180°.

The explosion can be initiated by striking the sample or by its exposure to oxidizable organic compounds.

The ozone can spontaneously ignite a piece of paper impregnated with an alcohol solution.

NFPA 704 four-colored diamond Health 4: Very short exposure could cause death or major residual injury. E.g. VX gas Flammability 4: Will rapidly or completely vaporize at normal atmospheric pressure and temperature, or is readily dispersed in air and will burn readily. Flash point below 23 °C (73 °F). E.g. propane Instability 4: Readily capable of detonation or explosive decomposition at normal temperatures and pressures. E.g. nitroglycerin Special hazard OX: Oxidizer. E.g. potassium perchlorate
