Figure 3
A magnified view of the face-sharing PbI6 octahedra and hydrogen-bonding scheme. Atoms labelled with an ampersand (&), a percentage sign (%), a hash (#), an asterisk (*) and an `at' sign (@) are at the symmetry positions (−x, y + , z), (−x + 1, y + , −z + 1), (−x + 1, −y + 1, −z + 1), (x, −y + , z) and (−x, −y + 1, −z), respectively. |
