Part of the crystal structure of (I) showing the formation of the [001] chain containing the cations and anions only. For the sake of clarity, H atoms have been omitted. Atoms marked with an asterisk (*), hash (#) or dollar sign ($) are at the symmetry positions (x, y, 1 + z), (1 − x, 2 − y, −z) and (1 − x, 2 − y, 1 − z), respectively. |
