(a) The sawtooth modulation [[01{\bar 1}]/3] in OYETET (Balijapalli et al., 2017BB4; [P{\bar 1}], Z′ = 6); neither the included water molecules nor the hydrogen bonds are shown. (b) The crenel modulation [201]/5 in UDICIU (Shintani et al., 2007BB36; P21, Z′ = 5). The molecules in the two groups have significantly different orientations and somewhat different conformations. (c) The crenel modulation [[12{\bar 1}]/5] in ZZZVTY04 (Kahr & Carter, 1992BB18; [P{\bar 1}], Z′ = 5). The Ph3CCl molecules in the two groups are conformational isomers. There is also a strong longitudinal component with the spacings in the group of three molecules being substantially shorter than the spacing in the group of two. (d) The [[01{\bar 1}]/5] modulation in XAPKOQ (Wu et al., 2010BB44; [P{\bar 1},] Z′ = 5) showing the ordered fault. Molecule 3 (in red) has a quite different conformation and is ca. 0.8 Å closer to its adjacent molecules than the other four molecules are to each other. Molecule 3 is also at the discontinuity of a subtle sawtooth modulation.
