The compound described by Gd2Co2Al crystallizes in the orthorhombic Immm space group. Gd(1) is bonded in a 10-coordinate geometry to six equivalent Co(1) and four equivalent Al(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent Gd(1), one Co(1), and two equivalent Al(1) atoms. Al(1) is bonded to eight equivalent Gd(1) and four equivalent Co(1) atoms to form a mixture of distorted face and edge-sharing AlGd8Co4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
