Figure 6
Part of the crystal structure of (1), showing the linking by the cations of the ladders along (x, , ) and (x, −, ) to form part of a (001) sheet. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (1 + x, y, z), (2 − x, −y, 1 − z) and (1 − x, −y, 1 − z), respectively. |
