NiCrAl crystallizes in the orthorhombic Imma space group. Cr(1) is bonded to two equivalent Cr(1) and four equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing CrCr2Ni4 cuboctahedra. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Cr(1), two equivalent Ni(1), and four equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms.
NiCrAl crystallizes in the orthorhombic Imma space group. Cr(1) is bonded to two equivalent Cr(1) and four equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing CrCr2Ni4 cuboctahedra. Both Cr(1)-Cr(1) bond lengths are 2.16 Å. All Cr(1)-Ni(1) bond lengths are 2.45 Å. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Cr(1), two equivalent Ni(1), and four equivalent Al(1) atoms. Both Ni(1)-Ni(1) bond lengths are 2.39 Å. All Ni(1)-Al(1) bond lengths are 2.60 Å. Al(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms.
