Manganese(II) sulfide Manganese(II) sulfide 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(II) sulfide can be prepared by reacting a manganese(II) salt (such as manganese(II) chloride) with ammonium sulfide: The crystal structure of manganese(II) sulfide is similar to that of sodium chloride. The pink color of MnS likely results from poor coupling between the lowest energy unoccupied Mn orbitals, resulting in discrete states rather than a delocalized band. Thus the lowest energy band-to-band electronic
Manganese, Minnesota crack through the concrete sidewalks. In the 1990s, a majority of the land was purchased. It is now privately owned and has a "no trespassing" sign posted on the gate of the southeastern part of the city. Presently, the area is consumed entirely by the growth of natural vegetation. Although the grid pattern of roads remains, the roads have either disintegrated or have been completely overtaken by grass, trees, and shrubs. The sheer height of the trees expose what has become of land once occupied by numerous buildings. Manganese is a classic example of a "ghost town." Manganese, Minnesota Manganese
