The compound described by Pr2Co2Al crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Co(1), and two equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
