Hauerite is a sulfide mineral in the pyrite group.It is the mineral form of Manganese(IV) disulfide MnS 2.It forms reddish brown or black octahedral crystals with the pyrite structure and it is usually found associated with the sulfides of other transition metals such as rambergite.
Manganese(II) sulfide is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite). [4]
A particularly common oxidation state for manganese in aqueous solution is +2, which has a pale pink color. Many manganese(II) compounds are known, such as the aquo complexes derived from manganese(II) sulfate (MnSO 4) and manganese(II) chloride (MnCl 2). This oxidation state is also seen in the mineral rhodochrosite (manganese(II) carbonate ...
Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
Alabandite or alabandine, formerly known as manganese blende or bluemenbachite is a rarely occurring manganese sulfide mineral. It crystallizes in the cubic crystal system with the chemical composition Mn 2+ S and develops commonly massive to granular aggregates, but rarely also cubic or octahedral crystals to 1 cm.
The pK a of HMn(CO) 5 in water is 7.1. [8] It is thus comparable to hydrogen sulfide, a common inorganic acid, in its acidity.. A common reaction involving HMn(CO) 5 is substitution of the CO ligands by organophosphines, as occurs both thermally and photochemically.
4), other combinations incorporating divalent, trivalent, or tetravalent cations, including magnesium, zinc, iron, manganese, aluminium, chromium, titanium, and silicon, are also possible. The anion is normally oxygen; when other chalcogenides constitute the anion sublattice the structure is referred to as a thiospinel .
