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.
The structure is distorted due to the Jahn–Teller effect. [3] At room temperature Mn 3 O 4 is paramagnetic , below 41-43 K, it is ferrimagnetic [ 12 ] although this has been reported as reducing in nanocrystalline samples to around 39 K. [ 13 ]

A story structure, narrative structure, or dramatic structure (also known as a dramaturgical structure) is the structure of a dramatic work such as a book, play, or film. There are different kinds of narrative structures worldwide, which have been hypothesized by critics, writers, and scholars over time.
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).
Drama is the specific mode of fiction represented in performance: a play, opera, mime, ballet, etc., performed in a theatre, or on radio or television. [1] Considered as a genre of poetry in general, the dramatic mode has been contrasted with the epic and the lyrical modes ever since Aristotle's Poetics (c. 335 BC)—the earliest work of dramatic theory.
Mise en abyme is not restricted to a specific kind of literature or art. The recursive appearance of a novel within a novel, a play within a play, a picture within a picture, or a film within a film form mises en abyme that can have many different effects on the perception and understanding of the literary text or work of art.
