The crystal structure described by Nd2Ni2Al crystallizes in the orthorhombic Immm space group. Nd(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Al(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Nd(1), two equivalent Ni(1), and two equivalent Al(1) atoms. Al(1) is bonded to eight equivalent Nd(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and edge-sharing AlNd8Ni4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
