Figure 2
The diffraction pattern of the title compound displays a pronounced subset of strong reflections (square) corresponding to the square net of iodides. The smaller black rectangle indicates the true reciprocal cell. The a* direction shows a sixfold superstructure caused by two effects: (i) the absence of every third Cu position along the a direction in every second row along the b direction, as indicated by the triple arrow in black, and (ii) the out-of-step arrangement of the counter-ion herringbone stacks, as indicated by the double arrows. The doubling of the cell along c is caused by the Cu defects being localized to every second row of Cu positions, and by the counter-ion stacking. All non-H atoms are shown as displacement ellipsoids at the 50% probability level. [See Fig. 1
