The crystal structure described by NbSi2 is Titanium Disilicide-like structured and crystallizes in the hexagonal P6_222 space group. Nb(1) is bonded in a 10-coordinate geometry to ten equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to five equivalent Nb(1) and five equivalent Si(1) atoms. is represented by the CIF file [CIF]
