Ni3Mn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mn is bonded to twelve equivalent Ni atoms to form MnNi12 cuboctahedra that share corners with twelve equivalent MnNi12 cuboctahedra, edges with twenty-four equivalent NiMn4Ni8 cuboctahedra, faces with six equivalent MnNi12 cuboctahedra, and faces with twelve equivalent NiMn4Ni8 cuboctahedra. All Mn–Ni bond lengths are 2.52 Å. Ni is bonded to four equivalent Mn and eight equivalent Ni atoms to form NiMn4Ni8 cuboctahedra that share corners with twelve equivalent NiMn4Ni8 cuboctahedra, edges with eight equivalent MnNi12 cuboctahedra, edges with sixteen equivalent NiMn4Ni8 cuboctahedra, faces with four equivalent MnNi12 cuboctahedra, and faces with fourteen equivalent NiMn4Ni8 cuboctahedra. All Ni–Ni bond lengths are 2.52 Å.
