Ni2Cr crystallizes in the orthorhombic Immm space group. Cr(1) is bonded to two equivalent Cr(1) and ten equivalent Ni(1) atoms to form CrCr2Ni10 cuboctahedra that share corners with two equivalent Cr(1)Cr2Ni10 cuboctahedra, corners with ten equivalent Ni(1)Cr5Ni7 cuboctahedra, edges with twelve equivalent Cr(1)Cr2Ni10 cuboctahedra, edges with twelve equivalent Ni(1)Cr5Ni7 cuboctahedra, faces with four equivalent Cr(1)Cr2Ni10 cuboctahedra, and faces with fourteen equivalent Ni(1)Cr5Ni7 cuboctahedra. Ni(1) is bonded to five equivalent Cr(1) and seven equivalent Ni(1) atoms to form NiCr5Ni7 cuboctahedra that share corners with five equivalent Cr(1)Cr2Ni10 cuboctahedra, corners with seven equivalent Ni(1)Cr5Ni7 cuboctahedra, edges with six equivalent Cr(1)Cr2Ni10 cuboctahedra, edges with eighteen equivalent Ni(1)Cr5Ni7 cuboctahedra, faces with seven equivalent Cr(1)Cr2Ni10 cuboctahedra, and faces with eleven equivalent Ni(1)Cr5Ni7 cuboctahedra.

Both Cr(1)-Cr(1) bond lengths are 2.45 Å. There are two shorter (2.45 Å) and eight longer (2.47 Å) Cr(1)-Ni(1) bond lengths. Ni(1) is bonded to five equivalent Cr(1) and seven equivalent Ni(1) atoms to form NiCr5Ni7 cuboctahedra that share corners with five equivalent Cr(1)Cr2Ni10 cuboctahedra, corners with seven equivalent Ni(1)Cr5Ni7 cuboctahedra, edges with six equivalent Cr(1)Cr2Ni10 cuboctahedra, edges with eighteen equivalent Ni(1)Cr5Ni7 cuboctahedra, faces with seven equivalent Cr(1)Cr2Ni10 cuboctahedra, and faces with eleven equivalent Ni(1)Cr5Ni7 cuboctahedra. There are three shorter (2.45 Å) and four longer (2.47 Å) Ni(1)-Ni(1) bond lengths.
