Nb3Si crystallizes in the cubic Pm-3n space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1) and four equivalent Si(1) atoms. Si(1) is bonded to twelve equivalent Nb(1) atoms to form a mixture of edge and face-sharing SiNb12 cuboctahedra.
Nb3Si crystallizes in the cubic Pm-3n space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1) and four equivalent Si(1) atoms. Both Nb(1)-Nb(1) bond lengths are 2.56 Å. All Nb(1)-Si(1) bond lengths are 2.87 Å. Si(1) is bonded to twelve equivalent Nb(1) atoms to form a mixture of edge and face-sharing SiNb12 cuboctahedra.
