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).
The BCS Examination (Bengali: বিসিএস পরীক্ষা) is a nationwide competitive examination in Bangladesh conducted by the Bangladesh Public Service Commission (BPSC) for recruitment to the various Bangladesh Civil Service cadres, including BCS (Administration), BCS (Audit & Accounts), BCS (Taxation), BCS (Customs and Excise), BCS (Foreign Affairs), and BCS (Police) among ...
BCS: 50 Years is a review volume on the topic of superconductivity edited by Leon Cooper, a 1972 Nobel Laureate in Physics, and Dmitri Feldman of Brown University, first published in 2010. [ 1 ]
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 ...
