The material structure described by Pr2Co12P7 crystallizes in the hexagonal P-6 space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 18-coordinate geometry to three equivalent Co(1), three equivalent Co(3), six equivalent Co(2), and six equivalent P(1) atoms.

In the fourth Co site, Co(4) is bonded in a 5-coordinate geometry to one P(1), two equivalent P(2), and two equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), one Co(4), two equivalent Co(1), two equivalent Co(2), and two equivalent Co(3) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to three equivalent Co(3) and six equivalent Co(4) atoms.
