Manganese(II) phosphate Manganese(II) phosphate Manganese(II) phosphate is an inorganic compound with the chemical formula Mn(PO). It is a rarely studied species, in contrast to the related lithium manganese phosphate, which has been investigated as a battery cathode. Manganese phosphates often combine with iron phosphates through paragenesis. In the process of paragenesis, each mineral affects the manner in which the other is crystallized. The minerals combine in isomorphic series, meaning that they crystallize in similar forms, producing a sequence of solids. Some examples of “isomorphic series” formed by Mn and Fe include heterosite (Fe,Mn)PO, purpurite (Mn,Fe)PO, and triplite (Mn,Fe)PO. The immersion method is
Manganese(II) chloride batteries. It is the precursor to the antiknock compound methylcyclopentadienyl manganese tricarbonyl. Manganism, or manganese poisoning, can be caused by long-term exposure to manganese dust or fumes. Manganese(II) chloride Manganese(II) chloride describes a series of compounds with the formula MnCl(HO), where the value of x can be 0, 2, or 4. The tetrahydrate is the most common form of "manganese(II) chloride" and is the tetrahydrate with the formula MnCl·4HO. The anhydrous form and a dihydrate MnCl·2HO are also known. Like many Mn(II) species, these salts are pink, with the paleness of the color being characteristic of transition metal complexes with
