Manganese(II) chloride

Manganese(II) chloride is the dichloride salt of manganese, MnCl₂. This inorganic chemical exists in the anhydrous form, as well as the dihydrate (MnCl₂·2H₂O) and tetrahydrate MnCl₂·4H₂O), with the tetrahydrate being the most common form. Like many Mn(II) species, these salts are pink, with the paleness of the color being characteristic of transition metal complexes with high spin d⁵ configurations.
