Figure 7
The average unit cell found by Roth et al. (2021 ) for both HH compounds. Nb (green) has a fractional occupancy 0.82 for the SC-0.81 crystal and 0.83 for the Q-0.84 #2 crystal. Co (orange) is split into four sites with 1/4 fractional occupancy each, and Sb (pink) is split into six sites each with a fractional occupancy of 1/6 (Roth et al., 2021 ). The figure was made with VESTA (Momma & Izumi, 2011 ). |
