WSi2 crystallizes in the tetragonal I4/mmm space group. W(1) is bonded in a distorted q6 geometry to ten equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to five equivalent W(1) and five equivalent Si(1) atoms.
WSi2 crystallizes in the tetragonal I4/mmm space group. W(1) is bonded in a distorted q6 geometry to ten equivalent Si(1) atoms. All W(1)-Si(1) bond lengths are 2.61 Å. Si(1) is bonded in a 10-coordinate geometry to five equivalent W(1) and five equivalent Si(1) atoms. There is one shorter (2.57 Å) and four longer (2.63 Å) Si(1)-Si(1) bond lengths.
