PrPdGa3 crystallizes in the tetragonal I-4m2 space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pd(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. Pd(1) is bonded to four equivalent Pr(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted PdPr4Ga8 cuboctahedra that share corners with four equivalent Ga(2)Pr4Ga4Pd4 cuboctahedra, corners with twelve equivalent Pd(1)Pr4Ga8 cuboctahedra, edges with two equivalent Ga(2)Pr4Ga4Pd4 cuboctahedra, faces with four equivalent Pd(1)Pr4Ga8 cuboctahedra, and faces with four equivalent Ga(2)Pr4Ga4Pd4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), two equivalent Pd(1), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded to four equivalent Pr(1), four equivalent Pd(1), and four equivalent Ga(1) atoms to form GaPr4Ga4Pd4 cuboctahedra that share corners with four equivalent Pd(1)Pr4Ga8 cuboctahedra, corners with twelve equivalent Ga(2)Pr4Ga4Pd4 cuboctahedra, edges with two equivalent Pd(1)Pr4Ga8 cuboctahedra, faces with four equivalent Pd(1)Pr4Ga8 cuboctahedra, and faces with four equivalent Ga(2)Pr4Ga4Pd4 cuboctahedra.
