Manganese(VII) oxide (manganese heptoxide) is an inorganic compound with the formula Mn 2 O 7 Manganese heptoxide is a volatile liquid with an oily consistency. It is a highly reactive and powerful oxidizer that reacts explosively with nearly any organic compound.
Other manganese oxides include Mn 5 O 8, Mn 7 O 12 and Mn 7 O 13. Minerals ... Psilomelane, Ba(Mn II)(Mn IV) 8 O 16 (OH) 4, or (Ba,H 2 O) 2 Mn 5 O 10; Pyrolusite, Mn ...
Each hydroxide ligand bridges to three Mn(II) sites. The O-H bonds are perpendicular to the planes defined by the oxygen atoms, projecting above and below these layers. [2] Manganese(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Mn 2+ salt: [3] Mn 2+ + 2 NaOH → Mn(OH) 2 + 2 Na ...
Complexes of Mn(IV) are well known, but they require elaborate ligands. Mn(IV)-OH complexes are an intermediate in some enzymes, including the oxygen evolving center (OEC) in plants. [33] Simple derivatives Mn 3+ are rarely encountered but can be stabilized by suitably basic ligands. Manganese(III) acetate is an oxidant useful in organic synthesis.
2 + 2 C → Mn + 2 CO. The key redox reactions of MnO 2 in batteries is the one-electron reduction: MnO 2 + e − + H + → MnO(OH) MnO 2 catalyses several reactions that form O 2. In a classical laboratory demonstration, heating a mixture of potassium chlorate and manganese dioxide produces oxygen gas.

This study showed that the Mn 2+ ions form a face centered cubic magnetic sub-lattice where there are ferromagnetically coupled sheets that are anti-parallel with adjacent sheets. Manganese(II) oxide undergoes the chemical reactions typical of an ionic oxide. Upon treatment with acids, it converts to the corresponding manganese(II) salt and ...
