Manganese oxide is any of a variety of manganese oxides and hydroxides. [1] These include Manganese(II) oxide, MnO; Manganese(II,III) oxide, Mn 3 O 4; Manganese(III) oxide, Mn 2 O 3; Manganese dioxide, MnO 2; Manganese(VI) oxide, MnO 3; Manganese(VII) oxide, Mn 2 O 7; Other manganese oxides include Mn 5 O 8, Mn 7 O 12 and Mn 7 O 13.
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. It was first described in 1860. [1] It is the acid anhydride of permanganic acid.
Manganese(IV) oxide is a blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc–carbon battery. [6] Manganese(VII) oxide is dark green in its crystalline form.
Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. These materials are white or pale pink solids.
Manganese oxalate is a chemical compound, a salt of manganese and oxalic acid with the chemical formula MnC 2 O 4. [2] [3] The compound creates light pink crystals, does not dissolve in water, and forms crystalline hydrates. [4] It occurs naturally as the mineral Lindbergite. [5]
Perrhenic acid is the chemical compound with the formula Re 2 O 7 (H 2 O) 2.It is obtained by evaporating aqueous solutions of Re 2 O 7.Conventionally, perrhenic acid is considered to have the formula HReO 4, and a species of this formula forms when rhenium(VII) oxide sublimes in the presence of water or steam.

Hausmannite is a complex oxide, or a mixed oxide, of manganese containing both di-and tri-valent manganese. Its chemical formula can be represented as Mn II Mn III 2 O 4, or more simply noted as MnO·Mn 2 O 3, or Mn 3 O 4, as commonly done for magnetite (Fe 3 O 4), the corresponding iron oxide. It belongs to the spinel group and forms ...
Nickel manganese oxides, [1] or nickel manganates, are spinel structure compounds of Nickel, Manganese and Oxygen of the form: Ni (x) Mn (3-x) O (y) [2] [3] Some common forms are Ni 2 MnO 4, NiMn 2 O 4, and Ni 1.5 Mn 1.5 O 4. They are most commonly formulated for use in thin film resistors and thermistors. [4]
