Materials Data on Nb4CoSi by Materials Project
CoNb4Si 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 Co and two equivalent Si atoms. Both Nb–Co bond lengths are 2.60 Å. Both Nb–Si bond lengths are 2.71 Å. Co is bonded in a 10-coordinate geometry to eight equivalent Nb and two equivalent Co atoms. Both Co–Co bond lengths are 2.51 Å. Si is bonded in a 10-coordinate geometry to eight equivalent Nb and two equivalent Si atoms. Both Si–Si bond lengths are 2.51 Å.
