Manganese(II) chloride is the dichloride salt of manganese, MnCl 2. This inorganic chemical exists in the anhydrous form, as well as the di hydrate (MnCl 2 ·2H 2 O) and tetrahydrate (MnCl 2 ·4H 2 O), with the tetrahydrate being the most common form.
It may be prepared in the manner common for other metallocenes, i.e., by reaction of manganese(II) chloride with sodium cyclopentadienide: MnCl 2 + 2 CpNa → Cp 2 Mn + 2 NaCl In the solid state below 159 °C, manganocene adopts a polymeric structure with every manganese atom coordinated by three cyclopentadienyl ligands, two of which are ...

Manganese(II) bromide is the chemical compound composed of manganese and bromine with the formula MnBr 2. It can be used in place of palladium in the Stille reaction , which couples two carbon atoms using an organotin compound .
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.
Manganese chloride may refer to: Manganese(II) chloride (manganous chloride, manganese dichloride), MnCl 2 , stable pink solid Manganese(III) chloride (manganic chloride, manganese trichloride), MnCl 3 , hypothetical chemical compound
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 ...
