Managnese(II) selenide is an inorganic compound with the chemical formula MnSe.

Manganese(II) selenide can be synthesized by the reaction of selenium powder and manganese(II) acetate in an alkaline solution with a reducing agent such as hydrazine at 180°C.[2]

Manganese selenide exists in three different polymorphs: the stable α-phase (NaCl type), the metastable γ-phase (wurtzite type) and unstable β phase (zincblende type).[1]
