Figure 3
Part of the crystal structure of 2-cyanoaniline (Laine et al., 1996

), showing the formation of a (10 $[\overline 1]$ ) sheet of R₄²(8) and R₄⁴(24) rings. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions ( $[{1 \over 2}]$ − x, y − $[{1 \over 2}]$ , $[{3 \over 2}]$ − z), ( $[{1 \over 2}]$ − x, $[{1 \over 2}]$ + y, $[{3 \over 2}]$ − z), ( $[{1 \over 2}]$ + x, $[-{1 \over 2}]$ − y, $[{1 \over 2}]$ + z) and (x − $[{1 \over 2}]$ , $[-{1 \over 2}]$ − y, z − $[{1 \over 2}]$ ), respectively.
