The compound described by Ba(PtGe3)4 crystallizes in the cubic Im-3 space group. Ba(1) is bonded to twelve equivalent Ge(1) atoms to form BaGe12 cuboctahedra that share faces with eight equivalent Pt(1)Ge6 octahedra. Pt(1) is bonded to six equivalent Ge(1) atoms to form distorted PtGe6 octahedra that share corners with six equivalent Pt(1)Ge6 octahedra and faces with two equivalent Ba(1)Ge12 cuboctahedra. The corner-sharing octahedral tilt angles are 60°. Ge(1) is bonded in a 5-coordinate geometry to one Ba(1), two equivalent Pt(1), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
