Figure 5
A view of part of the crystal structure of (II), showing the aggregation of three hydrogen-bonding motifs, viz. C22(6), R12(4) and R64(14). Hydrogen bonds are drawn as dotted lines. Atoms marked with an ampersand (&) or a dollar sign ($) are at the symmetry positions (x, y + 1, z) and (−x + , y + , z + ), respectively. One set of disordered ammonium H atoms and C-bound H atoms have been omitted. |
