NiS2 is pyrite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Ni4+ sites. In the first Ni4+ site, Ni4+ is bonded to six S2- atoms to form NiS6 octahedra that share corners with twelve NiS6 octahedra and corners with six SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 66°. There are a spread of Ni–S bond distances ranging from 2.35–2.38 Å. In the second Ni4+ site, Ni4+ is bonded to six S2- atoms to form NiS6 octahedra that share corners with twelve NiS6 octahedra and corners with six SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 65–66°. There are a spread of Ni–S bond distances ranging from 2.35–2.38 Å. In the third Ni4+ site, Ni4+ is bonded to six S2- atoms to form NiS6 octahedra that share corners with twelve NiS6 octahedra and corners with six SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 65–66°. There are a spread of Ni–S bond distances ranging from 2.35–2.38 Å. In the fourth Ni4+ site, Ni4+ is bonded to six S2- atoms to form NiS6 octahedra that share corners with twelve NiS6 octahedra and corners with six SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 65–66°. There are a spread of Ni–S bond distances ranging from 2.35–2.38 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 76°. The S–S bond length is 2.08 Å. In the second S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 75–76°. The S–S bond length is 2.08 Å. In the third S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 75°. The S–S bond length is 2.08 Å. In the fourth S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 75–76°. The S–S bond length is 2.08 Å. In the fifth S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 76°. In the sixth S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 76°. In the seventh S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedra tilt angles range from 76–77°. In the eighth S2- site, S2- is bonded to three Ni4+ and one S2- atom to form distorted SNi3S tetrahedra that share corners with three NiS6 octahedra and corners with fifteen SNi3S tetrahedra. The corner-sharing octahedral tilt angles are 76°.
