The material structure described by AlGd2Ni2 crystallizes in the orthorhombic Immm space group. Gd(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Gd(1), one 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. is represented by the Crystallographic Information File (CIF) [CIF]
