Figure 19
Part of the crystal structure of (VI) showing the formation of a hydrogen-bonded C(4) chain along [001]. For the sake of clarity, the H atoms bonded to C atoms have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( $[x, {1\over 2} - y, {1\over 2} + z]$ ) and ( $[x, {1\over 2} - y, -{1\over 2} + z]$ ), respectively.
