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).
Manganese is an essential human dietary element and is present as a coenzyme in several biological processes, which include macronutrient metabolism, bone formation, and free radical defense systems. Manganese is a critical component in dozens of proteins and enzymes. [8] The human body contains about 12 mg of manganese, mostly in the bones.
Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.

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.
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.
They conducted a narrative synthesis for outcomes that didn’t meet this and additional meta-analysis criteria. They were then able to conduct meta-analyses for inflammation, stress, and immunity
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.
