The crystal structure described by NiSi is Modderite structured and crystallizes in the orthorhombic Pnma space group. Ni(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to six equivalent Ni(1) and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
