Manganese Molybdate, MnMoO₄

Manganese Molybdate, MnMoO₄, is obtained in the anhydrous condition by fusing together sodium molybdate, manganous chloride, and sodium chloride. By treating normal or acid molybdate solutions with manganous salts, the manganese molybdate may be separated in the hydrated condition. Several hydrates have been described, but the existence of the monohydrate only appears to be established. This is a white crystalline powder.

Poly molybdates of manganese have not been obtained. A large number of complex salts have been described, on the composition of which, however, differing views have been expressed.
