The material structure described by Ni4W crystallizes in the tetragonal I4/m space group. W(1) is bonded to twelve Ni(1,1) atoms to form WNi12 cuboctahedra that share corners with twelve Ni(1,1)Ni9W3 cuboctahedra; edges with eight equivalent W(1)Ni12 cuboctahedra; edges with sixteen Ni(1,1)Ni9W3 cuboctahedra; faces with two equivalent W(1)Ni12 cuboctahedra; and faces with sixteen Ni(1,1)Ni9W3 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to three equivalent W(1) and nine Ni(1,1) atoms to form distorted NiNi9W3 cuboctahedra that share corners with three equivalent W(1)Ni12 cuboctahedra; corners with nine Ni(1,1)Ni9W3 cuboctahedra; edges with four equivalent W(1)Ni12 cuboctahedra; edges with twenty Ni(1,1)Ni9W3 cuboctahedra; faces with four equivalent W(1)Ni12 cuboctahedra; and faces with fourteen Ni(1,1)Ni9W3 cuboctahedra. In the second Ni site, Ni(1) is bonded to three equivalent W(1) and nine Ni(1,1) atoms to form distorted NiNi9W3 cuboctahedra that share corners with three equivalent W(1)Ni12 cuboctahedra; corners with nine Ni(1,1)Ni9W3 cuboctahedra; edges with four equivalent W(1)Ni12 cuboctahedra; edges with twenty Ni(1,1)Ni9W3 cuboctahedra; faces with four equivalent W(1)Ni12 cuboctahedra; and faces with fourteen Ni(1,1)Ni9W3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
