The structure described by Pr2PdGa12 crystallizes in the tetragonal P4/nbm space group. Pr(1) is bonded in a 14-coordinate geometry to two equivalent Ga(4), four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms. Pd(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(3) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Ga(2), and four equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Ga(1), and four equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 2-coordinate geometry to two equivalent Pr(1), two equivalent Pd(1), and two equivalent Ga(1) atoms. In the fourth Ga site, Ga(4) is bonded in a 4-coordinate geometry to one Pr(1), one Ga(4), and two equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
