The material structure described by Nb3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Nb(1) is bonded to eight equivalent Nb(1) and four equivalent Si(1) atoms to form NbNb8Si4 cuboctahedra that share corners with twelve equivalent Nb(1)Nb8Si4 cuboctahedra, edges with eight equivalent Si(1)Nb12 cuboctahedra, edges with sixteen equivalent Nb(1)Nb8Si4 cuboctahedra, faces with four equivalent Si(1)Nb12 cuboctahedra, and faces with fourteen equivalent Nb(1)Nb8Si4 cuboctahedra. Si(1) is bonded to twelve equivalent Nb(1) atoms to form SiNb12 cuboctahedra that share corners with twelve equivalent Si(1)Nb12 cuboctahedra, edges with twenty-four equivalent Nb(1)Nb8Si4 cuboctahedra, faces with six equivalent Si(1)Nb12 cuboctahedra, and faces with twelve equivalent Nb(1)Nb8Si4 cuboctahedra. is represented by the CIF card [CIF]
