ZnSi3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Zn(1) is bonded to twelve equivalent Si(1) atoms to form ZnSi12 cuboctahedra that share corners with twelve equivalent Zn(1)Si12 cuboctahedra, edges with twenty-four equivalent Si(1)Zn4Si8 cuboctahedra, faces with six equivalent Zn(1)Si12 cuboctahedra, and faces with twelve equivalent Si(1)Zn4Si8 cuboctahedra. Si(1) is bonded to four equivalent Zn(1) and eight equivalent Si(1) atoms to form SiZn4Si8 cuboctahedra that share corners with twelve equivalent Si(1)Zn4Si8 cuboctahedra, edges with eight equivalent Zn(1)Si12 cuboctahedra, edges with sixteen equivalent Si(1)Zn4Si8 cuboctahedra, faces with four equivalent Zn(1)Si12 cuboctahedra, and faces with fourteen equivalent Si(1)Zn4Si8 cuboctahedra.
