Yb2Ni2Al crystallizes in the orthorhombic Immm space group. Yb(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Yb(1), two equivalent Ni(1), and two equivalent Al(1) atoms. Al(1) is bonded to four equivalent Ni(1) atoms to form distorted edge-sharing AlNi4 cuboctahedra.
Yb2Ni2Al crystallizes in the orthorhombic Immm space group. Yb(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. There are four shorter (2.90 Å) and two longer (2.92 Å) Yb(1)-Ni(1) bond lengths. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Yb(1), two equivalent Ni(1), and two equivalent Al(1) atoms. There is one shorter (2.59 Å) and one longer (2.75 Å) Ni(1)-Ni(1) bond length. Both Ni(1)-Al(1) bond lengths are 2.41 Å. Al(1) is bonded to four equivalent Ni(1) atoms to form distorted edge-sharing AlNi4 cuboctahedra.
