The crystal structure described by PrPtGa3 crystallizes in the tetragonal I-4m2 space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. Pt(1) is bonded to four equivalent Pr(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted PtPr4Ga8 tetrahedra that share corners with four equivalent Ga(2)Pr4Ga4Pt4 cuboctahedra, corners with twelve equivalent Pt(1)Pr4Ga8 tetrahedra, edges with two equivalent Ga(2)Pr4Ga4Pt4 cuboctahedra, faces with four equivalent Ga(2)Pr4Ga4Pt4 cuboctahedra, and faces with four equivalent Pt(1)Pr4Ga8 tetrahedra. 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 Pt(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 Pt(1), and four equivalent Ga(1) atoms to form GaPr4Ga4Pt4 cuboctahedra that share corners with twelve equivalent Ga(2)Pr4Ga4Pt4 cuboctahedra, corners with four equivalent Pt(1)Pr4Ga8 tetrahedra, edges with two equivalent Pt(1)Pr4Ga8 tetrahedra, faces with four equivalent Ga(2)Pr4Ga4Pt4 cuboctahedra, and faces with four equivalent Pt(1)Pr4Ga8 tetrahedra. is represented by the CIF card [CIF]
