Materials Data on Ni3C by Materials Project
Ni3C is Upper Bainite-like structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Ni+1.33+ is bonded in a bent 120 degrees geometry to two equivalent C4- atoms. Both Ni–C bond lengths are 1.88 Å. C4- is bonded to six equivalent Ni+1.33+ atoms to form corner-sharing CNi6 octahedra. The corner-sharing octahedral tilt angles are 50°.
