The material structure described by NiSi is gamma CuTi structured and crystallizes in the orthorhombic Pmmn space group. Ni(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
