What is Manganese Chloride Tetrahydrate?

Manganese Chloride Tetrahydrate is an inorganic manganese salt with the manganese chloride tetrahydrate formula MnCl₂·4H₂O. It is the most common hydrated form of manganese(II) chloride and typically appears as pale pink crystals, a characteristic of high-spin manganese(II) compounds. The compound dissolves readily in water and contains four molecules of water of crystallization within its crystal structure. Manganese chloride tetrahydrate has also been studied as an oral magnetic resonance imaging (MRI) contrast agent and is recognized as a manganese coordination compound with nutraceutical significance.
