Zn3C is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Zn(1) is bonded to eight equivalent Zn(1) and four equivalent C(1) atoms to form distorted ZnZn8C4 cuboctahedra that share corners with twelve equivalent Zn(1)Zn8C4 cuboctahedra, edges with eight equivalent C(1)Zn12 cuboctahedra, edges with sixteen equivalent Zn(1)Zn8C4 cuboctahedra, faces with four equivalent C(1)Zn12 cuboctahedra, and faces with fourteen equivalent Zn(1)Zn8C4 cuboctahedra. C(1) is bonded to twelve equivalent Zn(1) atoms to form CZn12 cuboctahedra that share corners with twelve equivalent C(1)Zn12 cuboctahedra, edges with twenty-four equivalent Zn(1)Zn8C4 cuboctahedra, faces with six equivalent C(1)Zn12 cuboctahedra, and faces with twelve equivalent Zn(1)Zn8C4 cuboctahedra.
