Fe2MnGa is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Mn(1) is bonded to eight equivalent Fe(1) and four equivalent Ga(1) atoms to form MnGa4Fe8 cuboctahedra that share corners with four equivalent Mn(1)Ga4Fe8 cuboctahedra, corners with eight equivalent Ga(1)Mn4Fe8 cuboctahedra, edges with eight equivalent Mn(1)Ga4Fe8 cuboctahedra, edges with sixteen equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra, faces with four equivalent Mn(1)Ga4Fe8 cuboctahedra, faces with six equivalent Ga(1)Mn4Fe8 cuboctahedra, and faces with eight equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra. Fe(1) is bonded to four equivalent Mn(1), four equivalent Fe(1), and four equivalent Ga(1) atoms to form distorted FeMn4Ga4Fe4 cuboctahedra that share corners with twelve equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra, edges with eight equivalent Mn(1)Ga4Fe8 cuboctahedra, edges with eight equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra, edges with eight equivalent Ga(1)Mn4Fe8 cuboctahedra, faces with four equivalent Mn(1)Ga4Fe8 cuboctahedra, faces with four equivalent Ga(1)Mn4Fe8 cuboctahedra, and faces with ten equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra. Ga(1) is bonded to four equivalent Mn(1) and eight equivalent Fe(1) atoms to form GaMn4Fe8 cuboctahedra that share corners with four equivalent Ga(1)Mn4Fe8 cuboctahedra, corners with eight equivalent Mn(1)Ga4Fe8 cuboctahedra, edges with eight equivalent Ga(1)Mn4Fe8 cuboctahedra, edges with sixteen equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra, faces with four equivalent Ga(1)Mn4Fe8 cuboctahedra, faces with six equivalent Mn(1)Ga4Fe8 cuboctahedra, and faces with eight equivalent Fe(1)Mn4Ga4Fe4 cuboctahedra.
