Materials Data on Nb4SiNi by Materials Project
Nb4NiSi is Khatyrkite-derived structured and crystallizes in the tetragonal P4/mcc space group. The structure is three-dimensional. Nb is bonded in a 4-coordinate geometry to two equivalent Ni and two equivalent Si atoms. Both Nb–Ni bond lengths are 2.63 Å. Both Nb–Si bond lengths are 2.69 Å. Ni is bonded in a 10-coordinate geometry to eight equivalent Nb and two equivalent Ni atoms. Both Ni–Ni bond lengths are 2.49 Å. Si is bonded in a 10-coordinate geometry to eight equivalent Nb and two equivalent Si atoms. Both Si–Si bond lengths are 2.49 Å.
