W3Ni2N crystallizes in the cubic P4_132 space group. W(1) is bonded in a distorted bent 150 degrees geometry to six equivalent Ni(1) and two equivalent N(1) atoms. Ni(1) is bonded to nine equivalent W(1) and three equivalent Ni(1) atoms to form NiNi3W9 cuboctahedra that share corners with fifteen equivalent Ni(1)Ni3W9 cuboctahedra, edges with three equivalent N(1)W6 octahedra, faces with ten equivalent Ni(1)Ni3W9 cuboctahedra, and faces with four equivalent N(1)W6 octahedra. N(1) is bonded to six equivalent W(1) atoms to form distorted NW6 octahedra that share corners with six equivalent N(1)W6 octahedra, edges with six equivalent Ni(1)Ni3W9 cuboctahedra, and faces with eight equivalent Ni(1)Ni3W9 cuboctahedra. The corner-sharing octahedral tilt angles are 26°.
W3Ni2N crystallizes in the cubic P4_132 space group. W(1) is bonded in a distorted bent 150 degrees geometry to six equivalent Ni(1) and two equivalent N(1) atoms. There are a spread of W(1)-Ni(1) bond distances ranging from 2.72-2.81 Å. Both W(1)-N(1) bond lengths are 2.09 Å. Ni(1) is bonded to nine equivalent W(1) and three equivalent Ni(1) atoms to form NiNi3W9 cuboctahedra that share corners with fifteen equivalent Ni(1)Ni3W9 cuboctahedra, edges with three equivalent N(1)W6 octahedra, faces with ten equivalent Ni(1)Ni3W9 cuboctahedra, and faces with four equivalent N(1)W6 octahedra. All Ni(1)-Ni(1) bond lengths are 2.47 Å. N(1) is bonded to six equivalent W(1) atoms to form distorted NW6 octahedra that share corners with six equivalent N(1)W6 octahedra, edges with six equivalent Ni(1)Ni3W9 cuboctahedra, and faces with eight equivalent Ni(1)Ni3W9 cuboctahedra. The corner-sharing octahedral tilt angles are 26°.
