The crystal structure described by PtGe2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. Pt(1) is bonded to six equivalent Ge(1) atoms to form a mixture of edge and corner-sharing PtGe6 octahedra. The corner-sharing octahedral tilt angles are 55°. Ge(1) is bonded in a 4-coordinate geometry to three equivalent Pt(1) and one Ge(1) atom. is represented by the CIF file [CIF]
