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.[1]
Manganese selenide exists in three polymorphs. Most common is the stable α-phase (NaCl type).[2] There is also a metastable γ-phase (wurtzite type) and an unstable β phase (zincblende type).[1]
