[2] Like many metal sulfates, manganese sulfate forms a variety of hydrates: monohydrate, tetrahydrate, pentahydrate, and heptahydrate. All of these salts dissolve in water to give faintly pink solutions of the aquo complex [Mn(H 2 O) 6] 2+. The structure of MnSO 4 ·H 2 O has been determined by X-ray crystallography (see figure).
In Mn(CH 3) 2 (dmpe) 2, Mn(II) is low spin, which contrasts with the high spin character of its precursor, MnBr 2 (dmpe) 2 (dmpe = (CH 3) 2 PCH 2 CH 2 P(CH 3) 2). [38] Polyalkyl and polyaryl derivatives of manganese often exist in higher oxidation states, reflecting the electron-releasing properties of alkyl and aryl ligands.
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.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).

Polyatomic anions of the same element are named as the element name preceded by di-, tri-, etc., e.g.: O 2 2− dioxide(2−) (or peroxide as an acceptable name) C 2 2− dicarbide(2−) (or acetylide as an acceptable name) S 2 2− disulfide(2−) or sometimes as an alternative derived from a substitutive name e.g. S 2 2− disulfanediide
