EuNi3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Eu(1) is bonded to twelve equivalent Ni(1) atoms to form EuNi12 cuboctahedra that share corners with twelve equivalent Eu(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Eu4Ni8 cuboctahedra, faces with six equivalent Eu(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Eu4Ni8 cuboctahedra. Ni(1) is bonded to four equivalent Eu(1) and eight equivalent Ni(1) atoms to form distorted NiEu4Ni8 cuboctahedra that share corners with twelve equivalent Ni(1)Eu4Ni8 cuboctahedra, edges with eight equivalent Eu(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Eu4Ni8 cuboctahedra, faces with four equivalent Eu(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Eu4Ni8 cuboctahedra.
