The crystal structure described by NbNiSi crystallizes in the orthorhombic Pnma space group. Nb(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1) and five equivalent Si(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Nb(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Nb(1) and four equivalent Ni(1) atoms. is represented by the CIF file [CIF]
