NiSi2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. Ni(1) is bonded in a body-centered cubic geometry to eight equivalent Si(1) atoms. Si(1) is bonded to four equivalent Ni(1) and six equivalent Si(1) atoms to form a mixture of distorted corner, face, and edge-sharing SiSi6Ni4 tetrahedra.
