Manganese(VII) oxide, also known as permanganic acid and manganese heptoxide, is a chemical compound.

), green if in contact with sulfuric acid, explosive, strong oxidizer, very corrosive, This page was last edited on 15 September 2020, at 03:10. It produces ozone when it decomposes and this can ignite a piece of paper impregnated with alcohol. Mn2O7 can react further with sulfuric acid to give the remarkable manganyl(VII) cation MnO+3, which is isoelectronic with CrO3. Holleman, A. F.; Wiberg, E.

Except where otherwise noted, data are given for materials in their, ✪ Making Video Game Acid (Part I - Synthesizing Manganese Heptoxide), ✪ Manganese Heptoxide & Organic Solvents. To install click the Add extension button. The connectivity is indicated by the formula O3Mn−O−MnO3. Manganese heptoxide cannot be stored safely. The explosion can be initiated by striking the sample or by its exposure to oxidizable organic compounds. This is about the only +7 oxidation state compound of manganese that is not a permanganate. Its chemical formula is Mn2O7. The connectivity is indicated by the formula O 3 Mn-O-MnO 3. ), green if in contact with sulfuric acid. It is a powerful oxidizing agent.

Manganese heptoxide is an energetic material and will ignite nearly anything it contacts, including ethanol, acetone, cotton, polystyrene, aluminium and bread (albeit with great difficulty). It is also known to be able to explode on its own, so large quantities should never be prepared. Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. dark red oil (room temp. EINECS 235-025-8. This page was last changed on 4 May 2020, at 15:40. The vertices are occupied by oxygen atoms and at the centers of the tetrahedra are the Mn(VII) centers. It will set nearly any organic material on fire, and may explode on contact with metals. The terminal Mn−O distances are 1.585 Å and the bridging oxygen is 1.77 Å distant from the two Mn atoms. This is about the only +7 oxidation state compound of manganese that is not a permanganate.

Chem. Probably the most similar main group species is Cl2O7. It is either a dark red or green oil. In hot environments, this may also occur explosively. Manganese(VII) oxide (manganese heptoxide) is an inorganic compound with the formula Mn2O7. The production of manganese heptoxide is an undesirable byproduct in many situations. It is a dangerous explosive. This volatile liquid is highly reactive and more often discussed than intentionally prepared. It can be detonated by striking it or reacting it with some organic compounds such as alcohol. It is a dangerous oxidizer and was first described in 1860. The liquid is green by reflected light and red by transmitted light. Focusing on comparisons within the transition metal series, Tc2O7 and Mn2O7 are structurally similar but the Tc−O−Tc angle is 180°.
The products are MnO2 and O2. It melts at only 5.9 °C, and sublimes at −10 °C[clarification needed].

[3], Pyrosulfate, pyrophosphate, and dichromate adopt structures similar to that of Mn2O7. Focusing on comparisons within the transition metal series, Tc2O7 and Mn2O7 are structurally similar but the Tc-O-Tc angle is 180°. Ser. Manganese, chemical element that is a silvery white, hard, brittle metal of Group 7 in the periodic table. Manganese(VII) oxide, also known as permanganic acid and manganese heptoxide, is a chemical compound. Mn2O7 arises as a dark green oil by the addition of concentrated H2SO4 to KMnO4.
