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.
Mn 3 O 4 has the spinel structure, where the oxide ions are cubic close packed and the Mn II occupy tetrahedral sites and the Mn III octahedral sites. [3] The structure is distorted due to the Jahn–Teller effect. [3]
MnO has the distinction of being one of the first compounds [4] to have its magnetic structure determined by neutron diffraction, the report appearing in 1951. [5] 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.
α-Mn 2 O 3 has the cubic bixbyite structure, which is an example of a C-type rare earth sesquioxide (Pearson symbol cI80, space group Ia 3, #206). The bixbyite structure has been found to be stabilised by the presence of small amounts of Fe 3+ , pure Mn 2 O 3 has an orthorhombic structure ( Pearson symbol oP24, space group Pbca, #61).
Chemical literature databases correlate structures or other chemical information to relevant references such as academic papers or patents. This type of database includes STN, Scifinder, and Reaxys. Links to literature are also included in many databases that focus on chemical characterization.

ACD/ChemSketch allows for both basic structure drawing and importation of 3D and 2D .MDL files from other molecular modelling programs. ChemSketch has been favorably compared to other molecular modelling software, especially ChemDraw, based on its ability to display a wide range of structural components and the ease of creating complex structures quickly.
Manganese tetrafluoride is in equilibrium with manganese(III) fluoride and elemental fluorine: . MnF 4 ⇌ MnF 3 + 1 / 2 F 2. Decomposition is favoured by increasing temperature, and disfavoured by the presence of fluorine gas, but the exact parameters of the equilibrium are unclear, with some sources saying that MnF 4 will decompose slowly at room temperature, [14] [15] others placing ...
