The crystal structure described by Ge3Pt2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to one Ge(3), two equivalent Ge(1), and three equivalent Ge(2) atoms to form PtGe6 octahedra that share corners with four equivalent Pt(1)Ge6 octahedra,  a cornercorner with one Ge(2)GePt3 tetrahedra, and edges with two equivalent Pt(1)Ge6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the second Pt site, Pt(2) is bonded in a 6-coordinate geometry to three equivalent Ge(1) and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to two equivalent Pt(1) and three equivalent Pt(2) atoms. In the second Ge site, Ge(2) is bonded to three equivalent Pt(1) and one Ge(3) atom to form distorted GeGePt3 tetrahedra that share  a cornercorner with one Pt(1)Ge6 octahedra and corners with six equivalent Ge(2)GePt3 tetrahedra. The corner-sharing octahedral tilt angles are 74°. In the third Ge site, Ge(3) is bonded in a 5-coordinate geometry to one Pt(1), three equivalent Pt(2), and one Ge(2) atom. is represented by the CIF file [CIF]
