Figure 5
Visualization of octahedral networks of FAPbBr3 (left) and (D4)-FAPbBr3 (middle and right) at 10 K. (D4)-FAPbBr3 shows two symmetry-independent molecular positions in which the second molecule is strongly off-centred from the Br-lozenge centre. The atoms are number and colour coded as follows: hydrogen – 1, yellow; deuterium – 2, red; nitrogen – 3, light blue; carbon – 4, light grey, lead (octahedra) – grey; bromine – brown (edges of octahedra). |
