Managnese(II) molybdate is an inorganic compound with the chemical formula MnMoO4. α-MnMoO4 has a monoclinic crystal structure.[1] It is also antiferromagnetic at low temperatures.[2]

Applications

MnMoO4 has been used as active material in electrodes for aqueous supercapacitors[1][3] due to fast pseudocapacitive redox reactions, and as catalyst for hydrogen evolution.[3]
